Adapt dholland@'s fix to ufs_rename to fix PR kern/43582. Address several other MP locking issues discovered during the course of investigating the same problem. Removed extraneous vn_lock() calls on the Ifile, since the Ifile writes are controlled by the segment lock. Fix PR kern/45982 by deemphasizing the estimate of how much metadata will fill the empty space on disk when the disk is nearly empty (t_renamerace crates a lot of inode blocks on a tiny empty disk).

Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

The VATTR_NULL/VREF/VHOLD/HOLDRELE() macros lost their will to live years ago when the kernel was modified to not alter ABI based on DIAGNOSTIC, and now just call the respective function interfaces (in lowercase). Plenty of mix'n match upper/lowercase has creeped into the tree since then. Nuke the macros and convert all callsites to lowercase. no functional change

Move `struct dquot' and its supporting functions from quota.h to ufs_quota.c. - Make quota-internal functions static. - Clean up declarations in quota.h and ufs_extern.h. quota.h now has the description of quota criterions, on-disk structure, user-kernel interface and declaration of init/done functions. All ufs quota related function prototypes go to ufs_extern.h. - New functions ufsquota_init() and ufsquota_free() create or destroy the quota fields of `struct inode'. - chkdq() and chkiq() always update the quota fields of `struct inode' first. - Only ufs_access() explicitely calls getinoquota(). No objections on tech-kern@

- Increase the number of thread priorities from 128 to 256. How the space is set up is to be revisited. - Implement soft interrupts as kernel threads. A generic implementation is provided, with hooks for fast-path MD code that can run the interrupt threads over the top of other threads executing in the kernel. - Split vnode::v_flag into three fields, depending on how the flag is locked (by the interlock, by the vnode lock, by the file system). - Miscellaneous locking fixes and improvements.

- Pass the error number and residual count to biodone(), and let it handle setting error indicators. Prepare to eliminate B_ERROR. - Add a flag argument to brelse() to be set into the buf's flags, instead of doing it directly. Typically used to set B_INVAL. - Add a "struct cpu_info *" argument to kthread_create(), to be used to create bound threads. Change "bool mpsafe" to "int flags". - Allow exit of LWPs in the IDL state when (l != curlwp). - More locking fixes & conversion to the new API.

Changes to help the roll-forward agent, to wit: * Mark being-deleted files in the Ifile so we can finish deleting them at fs mount time. * Flag the Ifile with "cleaner must clean" when writers are waiting for the cleaner, rather than relying solely on the cleaner's estimation of whether it should clean or not. * Note partial segments written by a user agent (in particular, fsck_lfs) so that repeated rolls forward don't interfere with one another. * Add a new fcntl, LFCNPASS, that allows the log to wrap exactly once, for better testing of the validity of checkpoints. * Keep track of the on-disk nlink count when cleaning, so that we don't partially complete directory operations while cleaning. * Ensure that every single Ifile inode write represents a consistent view of the filesystem. In particular, the accounting for the segment we are writing the inode into must be correct, and the accounting for the segment that inode used to reside in must be correct. Rather than just rewriting the inode if we wrote it wrong, rewrite the necessary ifile blocks before writing the inode so we never write it wrong. * Don't unmark any VDIROP vnodes if we haven't written them to disk, avoiding yet another problem with the "wait for the cleaner" error return from lfs_putpages(). Also, move the last callback to an aiodone call, so we no longer do any memory management from interrupt context.

Make sure that we write all the pages on vnodes that are being flushed, even if we don't think there's room; drain v_numoutput before lfs_vflush() completes. Also, don't allow a vnode that is in the process of being cleaned to be chosen by getnewvnode(); this avoids a segment accounting panic in the case that a large number of inodes are fed to lfs_markv() all at once.

The default value used for existing filesystems is the same as the previous implicit value of (lfs_minfreeseg / 2 + 1), modulo some sanity checking. Count pending dirops on a per-filesystem basis, since once we start writing them we can't stop until we're done. This seems to help stave off the "no clean segments" panic in the case of filling the filesystem with directories and small files (e.g. simultaneously unpacking more copies of pkgsrc than will fit).

Optimize the free list search a little more; in particular use words instead of bytes for the index, and never search below fs->lfs_freehd. Fix a bug in the previous version of the search (an erroneous assumption that ino_t was signed). Free the bitmap when we unmount the filesystem.

Keep the free list ordered. This solves a problem first pointed out to me by Michel Oey, in which an aged LFS writes up to an extra Ifile block for every file created; and paves the way for the truncation of the Ifile when many files are deleted.

Various minor LFS improvements.
Kernel:
* Note when lfs_putpages(9) thinks it is not going to be writing any
pages before calling genfs_putpages(9). This prevents a situation in
which blocks can be queued for writing without a segment header.
* Correct computation of NRESERVE(), though it is still a gross
overestimate in most cases. Note that if NRESERVE() is too high, it
may be impossible to create files on the filesystem. We catch this
case on filesystem mount and refuse to mount r/w.
* Allow filesystems to be mounted whose block size is == MAXBSIZE.
* Somewhere along the line, ufs_bmaparray(9) started mangling UNWRITTEN
entries in indirect blocks again, triggering a failed assertion "daddr
<= LFS_MAX_DADDR". Explicitly convert to and from int32_t to correct
this. Should fix PR #29045.
* Add a high-water mark for the number of dirty pages any given LFS can
hold before triggering a flush. This is settable by sysctl, but off
(zero) by default.
* Be more careful about the MAX_BYTES and MAX_BUFS computations so we
shouldn't see "please increase to at least zero" messages.
* Note that VBLK and VCHR vnodes can have nonzero values in di_db[0]
even though their v_size == 0. Don't panic when we see this.
Fixes PR #26680.
* Change lfs_bfree to a signed quantity. The manner in which it is
processed before being passed to the cleaner means that sometimes it
may drop below zero, and the cleaner must be aware of this.
* Never report bfree < 0 (or higher than lfs_dsize) through
lfs_statfs(9). This prevents df(1) from ever telling us that our full
filesystems have 16TB free.
* Account space allocated through lfs_balloc(9) that does not have
associated buffer headers, so that the pagedaemon doesn't run us out
of segments.
* Return ENOSPC from lfs_balloc(9) when bfree drops to zero.
* Address a deadlock in lfs_bmapv/lfs_markv when the filesystem is being
unmounted. Because vfs_busy() is a shared lock, and
lfs_bmapv/lfs_markv mark the filesystem vfs_busy(), the cleaner can be
holding the lock that umount() is blocking on, then try to vfs_busy()
again in getnewvnode().
cleaner:
* Adapt lfs_cleanerd to use the fcntl call to get the Ifile filehandle,
so it need not be in the namespace.
* Make lfs_cleanerd be more careful when there are very few available
segments.
* Make lfs_cleanerd less verbose when the filesystem is unmounted.
newfs_lfs, fsck_lfs, and regression:
* Extend the lfs library from fsck_lfs(8) so that it can be used with a
not-yet-existent LFS. Make newfs_lfs(8) use this library, so it can
create LFSs whose Ifile is larger than one segment. Addresses PR #11110.
* Make newfs_lfs(8) use strsuftoi64() for its arguments, a la newfs(8).
* Make fsck_lfs(8) respect the "file system is clean" flag.
* Don't let fsck_lfs(8) think it has dirty blocks when invoked with the
-n flag.
* Remove the Ifile from the filesystem namespace. The cleaner now uses
a fcntl call on the root inode to find the Ifile filehandle. (As a
side-effect, addresses PR #29144.)

Keep per-inode, per-fs, and subsystem-wide counts of blocks allocated through lfs_balloc(), and use that to estimate the number of dirty pages belonging to LFS (subsystem or filesystem). This is almost certainly wrong for the case of a large mmap()ed region, but the accounting is tighter than what we had before, and performs much better in the typical case of pages dirtied through write().

Keep track of the highest block held by an LFS inode, so that we can be assured that the last byte of a file is always allocated. Previously a file extension could cause the filesystem to be flushed, writing an inconsistent inode to disk. Although this condition would be corrected the next time blocks were written to disk, an intervening crash would leave the filesystem in an inconsistent state, leaving fsck_lfs to complain of an inode "partially truncated".

Pull up revision 1.77 (requested by perseant in ticket #74): Make LFS dirops get their vnode first, before incrementing the dirop count, to prevent a deadlock trying to call VOP_PUTPAGES() on a VDIROP vnode. This can happen when a stacked filesystem is mounted on top of an LFS: an LFS dirop needs to get a vnode, which is available from the upper layer. The corresponding lower layer vnode, however, is VDIROP, so the upper layer can't be cleaned out since its VOP_PUTPAGES() is passed through to the lower layer, which waits for dirops to drain before it can proceed. Deadlock. Tweak ufs_makeinode() and ufs_mkdir() to pass the a_vpp argument through to VOP_VALLOC(). Partially addresses PR # 26043, though it probably does not completely fix the problem described there.

Add a new flag, IN_MODIFY. This is like IN_UPDATE|IN_CHANGE, but unlike setting those flags, it does not cause the inode to be written in the periodic sync. This is used for writes to special files (devices and named pipes) and FIFOs. Do not preemptively sync updates to access times and modification times. They are now updated in the inode only opportunistically, or when the file or device is closed. (Really, it should be delayed beyond close, but this is enough to help substantially with device nodes.) And the most amusing part: Trickle sync was broken on both FFS and ext2fs, in different ways. In FFS, the periodic call to VFS_SYNC(MNT_LAZY) was still causing all file data to be synced. In ext2fs, it was causing the metadata to *not* be synced. We now only call VOP_UPDATE() on the node if we're doing MNT_LAZY. I've confirmed that we do in fact trickle correctly now.

Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp *" argument that was added to vget(). Turns out that nothing actually used it! * Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). * Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc *" with "struct lwp *" in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed.

Add support for UFS2. UFS2 is an enhanced FFS, adding support for 64 bit block pointers, extended attribute storage, and a few other things. This commit does not yet include the code to manipulate the extended storage (for e.g. ACLs), this will be done later. Originally written by Kirk McKusick and Network Associates Laboratories for FreeBSD.

Add simple_lock protection for lfs_seglock and lfs_subsys_pages; these will be expanded to cover other per-fs and subsystem-wide data as well. Fix a case of IN_MODIFIED being set without updating lfs_uinodes, resulting in a "lfs_uinodes < 0" panic. Fix a deadlock in lfs_putpages arising from the need to busy all pages in a block; unbusy any that had already been busied before starting over.

Add code to UBCify LFS. This is still behind "#ifdef LFS_UBC" for now (there are still some details to work out) but expect that to go away soon. To support these basic changes (creation of lfs_putpages, lfs_gop_write, mods to lfs_balloc) several other changes were made, to wit: * Create a writer daemon kernel thread whose purpose is to handle page writes for the pagedaemon, but which also takes over some of the functions of lfs_check(). This thread is started the first time an LFS is mounted. * Add a "flags" parameter to GOP_SIZE. Current values are GOP_SIZE_READ, meaning that the call should return the size of the in-core version of the file, and GOP_SIZE_WRITE, meaning that it should return the on-disk size. One of GOP_SIZE_READ or GOP_SIZE_WRITE must be specified. * Instead of using malloc(...M_WAITOK) for everything, reserve enough resources to get by and use malloc(...M_NOWAIT), using the reserves if necessary. Use the pool subsystem for structures small enough that this is feasible. This also obsoletes LFS_THROTTLE. And a few that are not strictly necessary: * Moves the LFS inode extensions off onto a separately allocated structure; getting closer to LFS as an LKM. "Welcome to 1.6O." * Unified GOP_ALLOC between FFS and LFS. * Update LFS copyright headers to correct values. * Actually cast to unsigned in lfs_shellsort, like the comment says. * Keep track of which segments were empty before the previous checkpoint; any segments that pass two checkpoints both dirty and empty can be summarily cleaned. Do this. Right now lfs_segclean still works, but this should be turned into an effectless compatibility syscall.

Phase one of my three-phase plan to make LFS play nice with UBC, and bug-fixes I found while making sure there weren't any new ones. * Make the write clusters keep track of the buffers whose blocks they contain. This should make it possible to (1) write clusters using a page mapping instead of malloc, if desired, and (2) schedule blocks for rewriting (somewhere else) if a write error occurs. Code is present to use pagemove() to construct the clusters but that is untested and will go away anyway in favor of page mapping. * DEBUG now keeps a log of Ifile writes, so that any lingering instances of the "dirty bufs" problem can be properly debugged. * Keep track of whether the Ifile has been dirtied by various routines that can be called by lfs_segwrite, and loop on that until it is clean, for a checkpoint. Checkpoints need to be squeaky clean. * Warn the user (once) if the Ifile grows larger than is reasonable for their buffer cache. Both lfs_mountfs and lfs_unmount check since the Ifile can grow. * If an inode is not found in a disk block, try rereading the block, under the assumption that the block was copied to a cluster and then freed. * Protect WRITEINPROG() with splbio() to fix a hang in lfs_update.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Merge the short-lived perseant-lfsv2 branch into the trunk. Kernels and tools understand both v1 and v2 filesystems; newfs_lfs generates v2 by default. Changes for the v2 layout include: - Segments of non-PO2 size and arbitrary block offset, so these can be matched to convenient physical characteristics of the partition (e.g., stripe or track size and offset). - Address by fragment instead of by disk sector, paving the way for non-512-byte-sector devices. In theory fragments can be as large as you like, though in reality they must be smaller than MAXBSIZE in size. - Use serial number and filesystem identifier to ensure that roll-forward doesn't get old data and think it's new. Roll-forward is enabled for v2 filesystems, though not for v1 filesystems by default. - The inode free list is now a tailq, paving the way for undelete (undelete is not yet implemented, but can be without further non-backwards-compatible changes to disk structures). - Inode atime information is kept in the Ifile, instead of on the inode; that is, the inode is never written *just* because atime was changed. Because of this the inodes remain near the file data on the disk, rather than wandering all over as the disk is read repeatedly. This speeds up repeated reads by a small but noticeable amount. Other changes of note include: - The ifile written by newfs_lfs can now be of arbitrary length, it is no longer restricted to a single indirect block. - Fixed an old bug where ctime was changed every time a vnode was created. I need to look more closely to make sure that the times are only updated during write(2) and friends, not after-the-fact during a segment write, and certainly not by the cleaner.

Be more careful about when we update ctime/mtime. In particular, if we are only writing indirect blocks, that doesn't count for mtime; and when we first create a vnode, that certainly *does not* count for ctime (a bug that's been there from the beginning). This does not change the fact that mtime might still be set after write(2) is "completed", but it does make the atime-in-the-ifile code have some effect (noticeable less degradation of read time after an intervening large write).

Change disk addressing unit to be the fragment, instead of the disk sector. All quantities in the superblock, inodes, indirect blocks, etc. refer now to this abstract unit (called "fsb" as it is in FFS) instead of disk sectors; as a consequence segment summary blocks have to be multiples of a fragment in size. In v1 filesystems, compatibility code ensures that 1 fsb == 1 sector, regardless of fragment size. Fragments can now range in size between 512 and 32k; in the event that LFS_LABELPAD (8k) is smaller than the disk address unit size, an extra proto-superblock is kept at 8k from the beginning of the disk, to be used *only* to locate the real superblocks. (Not all of the userland knows about this yet.) Almost all of this was done not by me, but by joff.

Import of what I've been calling "LFSv2", that is, LFS with some features added that require changes to the on-disk data structures. These include: - 64-bit time in everything but inodes - User-specified segment offset, and segment size no longer restricted to PO2. - Serial number on segment summaries in addition to timestamp, and a new volume identifier, to make roll-forward feasible without fear of finding old data and thinking it was new. Although I think this version works at least as well as what's on the trunk, we're not done yet; hence this commit is going in on a branch and not on the trunk. Enhancements that are not here yet include fragment addressing, like FFS does, instead of block addressing.

Various bug-fixes to LFS, to wit: Kernel: * Add runtime quantity lfs_ravail, the number of disk-blocks reserved for writing. Writes to the filesystem first reserve a maximum amount of blocks before their write is allowed to proceed; after the blocks are allocated the reserved total is reduced by a corresponding amount. If the lfs_reserve function cannot immediately reserve the requested number of blocks, the inode is unlocked, and the thread sleeps until the cleaner has made enough space available for the blocks to be reserved. In this way large files can be written to the filesystem (or, smaller files can be written to a nearly-full but thoroughly clean filesystem) and the cleaner can still function properly. * Remove explicit switching on dlfs_minfreeseg from the kernel code; it is now merely a fs-creation parameter used to compute dlfs_avail and dlfs_bfree (and used by fsck_lfs(8) to check their accuracy). Its former role is better assumed by a properly computed dlfs_avail. * Bounds-check inode numbers submitted through lfs_bmapv and lfs_markv. This prevents a panic, but, if the cleaner is feeding the filesystem the wrong data, you are still in a world of hurt. * Cleanup: remove explicit references of DEV_BSIZE in favor of btodb()/dbtob(). lfs_cleanerd: * Make -n mean "send N segments' blocks through a single call to lfs_markv". Previously it had meant "clean N segments though N calls to lfs_markv, before looking again to see if more need to be cleaned". The new behavior gives better packing of direct data on disk with as little metadata as possible, largely alleviating the problem that the cleaner can consume more disk through inefficient use of metadata than it frees by moving dirty data away from clean "holes" to produce entirely clean segments. * Make -b mean "read as many segments as necessary to write N segments of dirty data back to disk", rather than its former meaning of "read as many segments as necessary to free N segments worth of space". The new meaning, combined with the new -n behavior described above, further aids in cleaning storage efficiency as entire segments can be written at once, using as few blocks as possible for segment summaries and inode blocks. * Make the cleaner take note of segments which could not be cleaned due to error, and not attempt to clean them until they are entirely free of dirty blocks. This prevents the case in which a cleanerd running with -n 1 and without -b (formerly the default) would spin trying repeatedly to clean a corrupt segment, while the remaining space filled and deadlocked the filesystem. * Update the lfs_cleanerd manual page to describe all the options, including the changes mentioned here (in particular, the -b and -n flags were previously undocumented). fsck_lfs: * Check, and optionally fix, lfs_avail (to an exact figure) and lfs_bfree (within a margin of error) in pass 5. newfs_lfs: * Reduce the default dlfs_minfreeseg to 1/20 of the total segments. * Add a warning if the sgs disklabel field is 16 (the default for FFS' cpg, but not usually desirable for LFS' sgs: 5--8 is a better range). * Change the calculation of lfs_avail and lfs_bfree, corresponding to the kernel changes mentioned above. mount_lfs: * Add -N and -b options to pass corresponding -n and -b options to lfs_cleanerd. * Default to calling lfs_cleanerd with "-b -n 4". [All of these changes were largely tested in the 1.5 branch, with the idea that they (along with previous un-pulled-up work) could be applied to the branch while it was still in ALPHA2; however my test system has experienced corruption on another filesystem (/dev/console has gone missing :^), and, while I believe this unrelated to the LFS changes, I cannot with good conscience request that the changes be pulled up.]

Clean up accounting of lfs_uinodes (dirty but unwritten inodes). Make lfs_uinodes a signed quantity for debugging purposes, and set it to zero as fs mount time. Enclose setting/clearing of the dirty flags (IN_MODIFIED, IN_ACCESSED, IN_CLEANING) in macros, and use those macros everywhere. Make LFS_ITIMES use these macros; updated the ITIMES macro in inode.h to know about this. Make ufs_getattr use ITIMES instead of FFS_ITIMES.

Fixes associated with filling an LFS: Change the space computation to appear to change the size of the *disk* rather than the *bytes used* when more segment summaries and inode blocks are written. Try to estimate the amount of space that these will take up when more files are written, so the disk size doesn't change too much. Regularize error returns from lfs_valloc, lfs_balloc, lfs_truncate: they now fail entirely, rather than succeeding half-way and leaving the fs in an inconsistent state. Rewrite lfs_truncate, mostly stealing from ffs_truncate. The old lfs_truncate had difficulty truncating a large file to a non-zero size (indirect blocks were not handled appropriately). Unmark VDIROP on fvp after ufs_remove, ufs_rmdir, so these can be reclaimed immediately: this vnode would not be written to disk again anyway if the removal succeeded, and if it failed, no directory operation occurred. ufs_makeinode and ufs_mkdir now remove IN_ADIROP on error.

If ifile blocks were written before dirops were complete, and then the system crashed, inodes could be allocated that were not referenced. (Though not a serious problem, it evidences itself in phase 4 of fsck_lfs.) Fix this by marking if_daddr with UNASSIGNED before the inodes are actually written; at mount time the ifile is checked for UNASSIGNED entries and any that are found are linked back into the free list. (The latter functionality should move into the roll-forward agent when it materializes.)

Make changes that will allow an LFS filesystem to be used as the root filesystem. In particular, - Fix mknod deadlock, described in PR 8172. - Enable lfs_mountroot. - Make lfs_writevnodes treat filesystems mounted on lfs device nodes properly, by flushing that device rather than trying to add blocks to the device inode. This, in combination with lfs boot blocks, will allow operation of an all-lfs system.

Rudimentary support for LFS under UBC:
- LFS-specific VOP_BALLOC and VOP_PUTPAGES vnode ops.
- getblk VREG panic #ifdef'd out (can be reinstated when Ifile is
internalized and Ifile can be made another type from VREG)
- interface to VOP_PUTPAGES changed to pass all pager flags, not
just sync. FS putpages routines must know about the pager flags.
- new LFS magic disk address, -2 ("unwritten"), meaning accounted for
but not assigned to a fixed disk location (since LFS does these two
things separately, and the previous accounting method using buffer
headers no longer will work). Changed references to (foo == (daddr_t)-1)
to (foo < 0). Since disk drivers reject all addresses < 0, this should
not present a problem for other FSs.

Pull up src/sys/ufs/lfs: lfs_alloc.c 1.19->1.21. This fixes another locking problem, this time a lock on ufs_hashlock in lfs_vfree. The lock could be held by a process calling getnewvnode, and then attempted again by lfs_vfree. This works around that, not attempting to get the lock if curproc already holds it.

Pull-up of changes made to the trunk on Sunday [1.18->1.19], to wit: Take out the `#ifdef USE_UFSHASH'; use ufs_hashlock to lock the inode free list instead of free_lock. Fix inode reporting in lfs_statfs (the meaning of f_files and f_ffree was reversed). Fix "lfs_ifind: dinode xxx not found" panic. When inodes were freed, then immediately reloaded, their dinodes were located in an inode block which was not on disk at the advertized location, nor in the cache (although it would be flushed to disk next segment write). Fix this by using getblk() instead of lfs_newbuf() for inode blocks. Better checking for held inode locks in lfs_fastvget, for a number of error conditions. Also change the default setting of lfs_clean_vnhead to 0, which seems to make the locking problems go away (although this is difficult to test as I can't reliably reproduce them). Make sure that the wakeup occurs for vnodes that lfs_update might be sleeping on (nodes which are not marked IN_MODIFIED/IN_CLEANING, but which have dirty buffers), by marking them with the appropriate flag if dirtybuffers were added while the write was in progress. Fix block counting during file truncation, if not truncating to zero. Disallow threshold-initiated cache flush when dirops are active. Also, make SET_ENDOP use lfs_check instead of inlining most of it. Improve the debugging printfs in the cleaner syscalls (in particular, make it obvious that they're coming from lfs). Check the superblock version field, and refuse to mount the filesystem if the version number is higher than we know about. This allows, e.g., changes in the format of the ifile, segment size restrictions and boundaries, etc., which would not affect existing fields in the superblock, but which would drastically affect the filesystem, to be smoothly integrated at a later date.

New sources should leave the LFS in a more-or-less working state. Changes include: - DIROP segregation is enabled, and greater care is taken to make sure that a checkpoint completes. Fsck is not needed to remount the filesystem. - Several checks to make sure that the LFS subsystem does not overuse various resources (memory, in particular). - The cleaner routines, lfs_markv in particular, are completely rewritten. A buffer overflow is removed. Greater care is taken to ensure that inodes come from where lfs_cleanerd say they come from (so we know nothing has changed since lfs_bmapv was called). - Fragment allocation is fixed, so that writes beyond end-of-file do the right thing.

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.

Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h:
- added an "union inode_ext" to struct inode, for the per-fs extentions.
For now only ext2fs uses it.
- i_din is now an union:
union {
struct dinode ffs_din; /* 128 bytes of the on-disk dinode. */
struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
} i_din
Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
macro, depending on the time of the inode. ITIMES is used where necessary,
FFS_ITIMES and EXT2FS_ITIMES in other places.
