Add inline functions to manipulate the klists that link up knotes
via kn_selnext:

- klist_init()
- klist_fini()
- klist_insert()
- klist_remove()

These provide some API insulation from the implementation details of these
lists (but not completely; see vn_knote_attach() and vn_knote_detach()).
Currently just a wrapper around SLIST(9).

This will make it significantly easier to switch kn_selnext linkage
to a different kind of list.

introduce vfs.generic.timestamp_precision sysctl to control precision
of the timer used for vfs_timestamp(); default stays the same
to use nanotime(9), but option is there to use the faster, albeit
less precise methods

vnode/fsnode pair:

int
vcache_new(struct mount *mp, struct vnode *dvp, struct vattr *vap,
    kauth_cred_t cred, struct vnode **vpp)

where dvp is the (referenced) directory where we want to create the
new node, vap passes va_type, va_mode and possibly va_rdev and cred
gives the credentials to setup uid/guid.

The node returned from vcache_new() is referenced, fully initialised
and has link count zero.

   src/sys/ufs/ufs/ufs_quota.c 1.116
   src/lib/libquota/quota_kernel.c 1.5

and do them correctly.

If you're going to change the name of something, you need to change
the name of *all* the things with the same name, not just a handful,
and you should change it to something similar so it still matches the
rest of the system rather than just picking an arbitrarily different
name.

Hi, Joerg.

To wit, rename the quotactl "delete" operation to "del", because
"delete" is a reserved word in C++ and for some reason Joerg wants to
run internal interfaces used only by C code through his C++ compiler.
Do not rename it to "remove" instead, because this doesn't match
libquota or the rest of the usage throughout the system; and rename
all the related identifiers, not just the ones that blew the mind of
Joerg's C++ compiler.

Because this is not a user-facing API (the only userland consumer
sys/quotactl.h is libquota) it is sort of ok to make arbitrary
source-incompatible changes; however, by the same token it's completely
unnecessary. If it *were* a user-facing API that someone might have a
semi-rational reason to want to run a C++ compiler on, it would be
incorrect to change it at this point.

Add a global vnode cache:

- vcache_get() retrieves a referenced and initialised vnode / fs node pair.
- vcache_remove() removes a vnode / fs node pair from the cache.

On cache miss vcache_get() calls new vfs operation vfs_loadvnode() to
initialise a vnode / fs node pair.  This call is guaranteed exclusive,
no other thread will try to load this vnode / fs node pair.

Convert ufs/ext2fs, ufs/ffs and ufs/mfs to use this interface.

Remove now unused ufs/ufs_ihash

Discussed on tech-kern.

Current support for iterating over mnt_vnodelist is rudimentary.  Every
caller has to care about list and vnode mutexes, reference count being zero,
intermediate vnode states like VI_CLEAN, VI_XLOCK, VI_MARKER and so on.

Add an interface to iterate over a vnode list:

void vfs_vnode_iterator_init(struct mount *mp, struct vnode_iterator **marker)
void vfs_vnode_iterator_destroy(struct vnode_iterator *marker)
bool vfs_vnode_iterator_next(struct vnode_iterator *marker, struct vnode **vpp)

vfs_vnode_iterator_next() returns either "false / *vpp == NULL" when done
or "true / *vpp != NULL" to return the next referenced vnode from the list.

To make vrecycle() work in this environment change it to

bool vrecycle(struct vnode *vp)

where "vp" is a referenced vnode to be destroyed if this is the last reference.

Add an accessor -- ufs_maxphys() -- to check the maximum transfer size
for a given UFS mountpoint, and move the code from mount that finds
the underlying disk and resets the mountpoint max transfer size into a
utility function, ufs_update_maxphys().

Add a global serial number that counts disk property changes to which
filesystems are meant to accomodate themselves.  Make ufs_maxphys()
check it.  This is a sort of flag-polling interface that avoids callbacks
into the filesystem code, but will require freezing filesystems and
draining in-flight transactions before a decrease in size that is
mandatory (like attaching a disk with a smaller maximum transfer size
as a spare in a RAIDframe set), rather than "advisory", like finding
out set geometry from a RAID controller long after boot and deciding
a smaller transfer size would be optimal, can be signalled.  Still, the
"advisory" case is the common one so this is progress.

Make a bit of an example of RAIDframe by making it bump this new
serial number when disks are added to the subsystem.  I will attack
one of the hardware RAID drivers (probably arcmsr) next.

Initial snapshot of work to eliminate 64K MAXPHYS.  Basically works for
physio (I/O to raw devices); needs more doing to get it going with the
filesystems, but it shouldn't damage data.

All work's been done on amd64 so far.  Not hard to add support to other
ports.  If others want to pitch in, one very helpful thing would be to
sort out when and how IDE disks can do 128K or larger transfers, and
adjust the various PCI IDE (or at least ahcisata) drivers and wd.c
accordingly -- it would make testing much easier.  Another very helpful
thing would be to implement a smart minphys() for RAIDframe along the
lines detailed in the MAXPHYS-NOTES file.

   - discard proplib interpreter code in vfs_quotactl.c
   - add dispatching code for the 14 quotactl ops in vfs_quotactl.c
   - mark the proplib quotactl syscall obsolete
   - add a new syscall number for the new quotactl syscall
   - change the name of the syscall to __quotactl()
   - remove the decl of the old quotactl from quota/quotaprop.h
   - add a decl of the new quotactl to sys/quotactl.h
   - update the libc build

As a precaution, add sys/param.h explicitly to some headers that will
no longer get it via sys/ucred.h and don't already include it
explicitly. These should in turn be removed when it can be confirmed
that it's safe to do so. (Because sys/param.h is full of things that
are often tested with #if, it's not in general safe to remove it
without checking, as such tests fail silently if the symbol goes
missing.)

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Snapshot of work in progress on a modernised disk quota system:
- new quotactl syscall (versionned for backward compat), which takes
  as parameter a path to a mount point, and a prop_dictionary
  (in plistref format) describing commands and arguments.
  For each command, status and data are returned as a prop_dictionary.
  quota commands features will be added to take advantage of this,
  exporting quota data or getting quota commands as plists.

- new on disk-format storage (all 64bit wide), integrated to metadata for
  ffs (and playing nicely with wapbl).
  Quotas are enabled on a ffs filesystem via superblock flags.
  tunefs(8) can enable or disable quotas.
  On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid
  block and inode usages, and will check and update quotas in Pass 6.
  quota usage and limits are stored in unliked files (one for users,
  one for groups)l fsck_ffs(8) will create the files if needed, or
  free them if needed. This means that after enabling or disabling
  quotas on a filesystem; a fsck_ffs(8) run is required.
  quotacheck(8) is not needed any more, on a unclean shutdown
  fsck or journal replay will take care of fixing quotas.
  newfs(8) can create a ready-to-mount quota-enabled filesystem
  (superblock flags are set and quota inodes are created).
  Other new features or semantic changes:
  - default quota datas, applied to users or groups which don't already
    have a quota entry
  - per-user/group grace time (instead of a filesystem global one)
  - 0 really means "nothing allowed at all", not "no limit".
    If you want "no limit", set the limit to UQUAD_MAX (tools will
    understand "unlimited" and "-")

  A quota file is structured as follow:
  it starts with a header, containing a few per-filesystem values,
  and the default quota limits.
  Quota entries are linked together as a simple list, each entry has a
  pointer (as an offset withing the file) to the next.
  The header has a pointer to a list of free quota entries, and
  a hash table of in-use entries. The size of the hash table depends
  on the filesystem block size (header+hash table should fit in the
  first block). The file is not sparse and is a multiple of
  filesystem block size (when the free quota entry list is empty a new
  filesystem block is allocated). quota entries to not cross
  filesystem block boundaries.

  In memory, the kernel keeps a cache of recently used quota entries
  as a reference to the block number, and offset withing the block.
  The quota entry itself is keept in the buf cache.

fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with
related atf tests :)
The kernel can update disk usage and report it via quotactl(2).

Todo: enforce quotas limits (limits are not checked by kernel yet)
      update repquota, edquota and rpc.rquotad to the new world
      implement compat_50_quotactl ioctl.
      update quotactl(2) man page

fsck_ffs required fixes so that allocating new blocks or inodes will
properly update the superblock and cg sumaries. This was not an issue up
to now because superblock and cg sumaries check happened last, but now
allocations or frees can happen in pass 6.

- Add usermount_common_policy() that implements some common (everything
  but access control) user mounting policies: enforced MNT_NOSUID and
  MNT_NODEV, no MNT_EXPORT, MNT_EXEC propagation. This can be useful for
  secmodels that are interested in simply adding finer grained user mount
  support.

- Add a mount subsystem listener for KAUTH_REQ_SYSTEM_MOUNT_GET.

Import read-only part of the NiLFS (v2) implementation for NetBSD. It has been
tested with a DEBUG+DIAGNOSTIC+LOCKDEBUG kernel. To summerise NiLFS, i'll
repeat my posting to tech-kern here:

NiLFS stands for New implementation of Logging File System; LFS done
right they claim :) It is at version 2 now and is being developed by NTT, the
Japanese telecom company and recently put into the linux source tree. See
http://www.nilfs.org. The on-disc format is not completely frozen and i expect
at least one minor revision to come in time.

The benefits of NiLFS are build-in fine-grained checkpointing, persistent
snapshots, multiple mounts and very large file and media support. Every
checkpoint can be transformed into a snapshot and v.v. It is said to perform
very well on flash media since it is not overwriting pieces apart from a
incidental update of the superblock, but that might change. It is accompanied
by a cleaner to clean up the segments and recover lost space.

My work is not a port of the linux code; its a new implementation. Porting the
code would be more work since its very linux oriented and never written to be
ported outside linux. The goal is to be fully interchangable. The code is non
intrusive to other parts of the kernel. It is also very light-weight.

The current state of the code is read-only access to both clean and dirty
NiLFS partitions. On mounting a dirty partition it rolls forward the log to
the last checkpoint. Full read-write support is however planned!

Just as the linux code, mount_nilfs allows for the `head' to be mounted
read/write and allows multiple read-only snapshots/checkpoint mounts next to
it.

By allowing the RW mount at a different snapshot for read-write it should be
possible eventually to revert back to a previous state; i.e. try to upgrade a
system and being able to revert to the exact state prior to the upgrade.

Compared to other FS's its pretty light-weight, suitable for embedded use and
on flash media. The read-only code is currently 17kb object code on
NetBSD/i386. I doubt the read-write code will surpass the 50 or 60. Compared
this to FFS being 156kb, UDF being 84 kb and NFS being 130kb. Run-time memory
usage is most likely not very different from other uses though maybe a bit
higher than FFS.

PR kern/38141 lookup/vfs_busy acquire rwlock recursively

Simplify the mount locking. Remove all the crud to deal with recursion on
the mount lock, and crud to deal with unmount as another weirdo lock.

Hopefully this will once and for all fix the deadlocks with this. With this
commit there are two locks on each mount:

- krwlock_t mnt_unmounting. This is used to prevent unmount across critical
  sections like getnewvnode(). It's only ever read locked with rw_tryenter(),
  and is only ever write locked in dounmount(). A write hold can't be taken
  on this lock if the current LWP could hold a vnode lock.

- kmutex_t mnt_updating. This is taken by threads updating the mount, for
  example when going r/o -> r/w, and is only present to serialize updates.
  In order to take this lock, a read hold must first be taken on
  mnt_unmounting, and the two need to be held across the operation.

One effect of this change: previously if an unmount failed, we would make a
half hearted attempt to back out of it gracefully, but that was unlikely to
work in a lot of cases. Now while an unmount that will be aborted is in
progress, new file operations within the mount will fail instead of being
delayed. That is unlikely to be a problem though, because if the admin
requests unmount of a file system then s(he) has made a decision to deny
access to the resource.

kern/38135 vfs_busy/vfs_trybusy confusion

The symptom was that sometimes file systems would occasionally not appear
in output from 'df' or 'mount' if the system was busy. Resolution:

- Make mount locks work somewhat like vm_map locks.
- vfs_trybusy() now only fails if the mount is gone, or if someone is
  unmounting the file system. Simple contention on mnt_lock doesn't
  cause it to fail.
- vfs_busy() will wait even if the file system is being unmounted.

Add some devfs code that's been sitting in my local tree for a while.

devfsd(8) is now the first daemon to be started after init(8). It tracks
device insertion (will eventually track removal) and devfs mounts.

Currently, we can mount multiple device file systems and have device
special files pushed into the mounts automatically, though, the device
special files aren't created with the correct major/minor number pairs
yet.

More work to come soon.

PR kern/37706 (forced unmount of file systems is unsafe):

- Do reference counting for 'struct mount'. Each vnode associated with a
  mount takes a reference, and in turn the mount takes a reference to the
  vfsops.
- Now that mounts are reference counted, replace the overcomplicated mount
  locking inherited from 4.4BSD with a recursable rwlock.

Fix some race conditions in rename.
Introduce a per-FS rename lock and new vfsops to manipulate it.
Get this lock while renaming. Also add another relookup() in do_sys_rename,
which is a hack to kludge around some of the worst deficiencies of
ufs_rename.

Don't use the 'specificdata' system to store per-mountpoint information

- Don't do proc_vmspace_getref() in dofileread() and friends. They only
  ever access the caller's vmspace so it's not going to go away. Instead
  just use curproc->p_vmspace. Fixes high lock contention during file I/O
  by multithreaded processes. Don't pass in lwp_t *l, it's confusing.

- Drain cleaned vnodes from mountpoints just before checking to see
  if there are danglers. Cleaned vnodes now stick around on mountpoint
  lists until reused, as it's too expensive to pull them off earlier.

Split the work for sys_stat, sys_lstat, sys_fstat and sys_fhstat out into
separate functions that don't do the copyout.
This allows all the compat_xxx versions to convert the 'struct stat' to
the correct format without using the 'stackgap'.
The stackgap isn't at all LWP friendly, and needs to be removed from
any compat functions that might involve threads (inc. clone()).
The code is still binary compatible with existing LKMs.

New file system suspension API to replace vn_start_write and vn_finished_write.
The suspension helpers are now put into file system specific operations.
This means every file system not supporting these helpers cannot be suspended
and therefore snapshots are no longer possible.

Implemented for file systems of type ffs.

The new API is enabled on a kernel option NEWVNGATE.  This option is
not enabled by default in any kernel config.

Presented and discussed on tech-kern with much input from
Bill Studenmund <wrstuden@netbsd.org> and YAMAMOTO Takashi <yamt@netbsd.org>.

Welcome to 4.99.9 (new vfs op vfs_suspendctl).

Replace the LIST structure mp->mnt_vnodelist to a TAILQ structure since all
vnodes were synced and processed backwards. This meant that the last
accessed node was processed first and the earlierst last.

An extra benefit is the removal of the ugly hack from the Berkly days on
LFS.

In the proces, i've also replaced the various variations hand written loops
by the TAILQ_FOREACH() macro's.

some filehandle syscall related changes.

- remove the support of variable-sized filehandle from compat version of
  syscalls.  (strictly speaking, it breaks abi.  i don't think it's a problem
  because this feature is short-lived and there are no affected in-tree
  filesystems.)
- unify vfs_copyinfh_alloc and vfs_copyinfh_alloc_size.
- vfs_copyinfh_alloc_size: check fhsize strictly.
- reduce code duplication between compat and current syscalls.

Apply the NFS exports list rototill patch:

- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
  function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
  file sys/nfs/nfs_export.c.  The former was becoming large and its code
  is always compiled, regardless of the build options.  Using the latter,
  the code is only compiled in when NFSSERVER is enabled.  While doing this,
  also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
  path and a set of export entries.  At the moment it can only clear the
  exports list or append entries, one by one, but it is done in a way that
  allows setting the whole set of entries atomically in the future (see the
  comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
  that it becomes file system agnostic.  In fact, all this whole thing was
  done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
  exports initialization; done internally by the kernel when initializing
  the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
  subsystems can run arbitrary code upon receipt of specific VFS events.
  At the moment, this only provides support for unmount and is used to
  destroy NFS exports lists from the file systems being unmounted, though it
  has room for extension.

Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments
and advice in the development of this patch.

Initial addition of tmpfs, an efficient memory file-system.  This project
was developed as part of Google's Summer of Code 2005 program.  This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*.  Therefore, it is disabled by
default in all kernels.  However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

OK'ed by my project mentor, William Studenmund (wrstuden@).

* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),

Fixing age old cruft:
* Rather than using mnt_maxsymlinklen to indicate that a file systems returns
  d_type fields(!), add a new internal flag, IMNT_DTYPE.

Add 3 new elements to ufsmount:
* um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed
  in the first place).
* um_dirblksiz, which tracks the current directory block size, eliminating the
  FS-specific checks littered throughout the code.  This may be used later to
  make the block size variable.
* um_maxfilesize, which is the maximum file size, possibly adjusted lower due
  to implementation issues.

* ffs_lookup.c 1.21, 1.28, 1.33, 1.48

- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

Dynamic sysctl.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

Add the gating of system calls that cause modifications to the underlying
file system.
The function vfs_write_suspend stops all new write operations to a file
system, allows any file system modifying system calls already in progress
to complete, then sync's the file system to disk and returns. The
function vfs_write_resume allows the suspended write operations to
complete.

From FreeBSD with slight modifications.

Add a new feature-test macro, _NETBSD_SOURCE.  If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
  can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
  various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
  !defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them.  In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

PR/1796: John Kohl: statfs misbehaves under chrooted environments.

- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
  and factored out some of the vfsop statfs() code to copy_statfs_info(). This
  fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.

adjusted via sysctl.  file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value.  the max number of FFS softdeps is also recalculated.

Fix assorted bugs around shutdown/reboot/panic time.
 - add a new global variable, doing_shutdown, which is nonzero if
vfs_shutdown() or panic() have been called.
- in panic, set RB_NOSYNC if doing_shutdown is already set on entry
so we don't reenter vfs_shutdown if we panic'ed there.
 - in vfs_shutdown, don't use proc0's process for sys_sync unless
curproc is NULL.
 - in lockmgr, attribute successful locks to proc0 if doing_shutdown
&& curproc==NULL, and  panic if we can't get the lock right away; avoids the
spurious lockmgr DIAGNOSTIC panic from the ddb reboot command.
 - in subr_pool, deal with curproc==NULL in the doing_shutdown case.
 - in mfs_strategy, bitbucket writes if doing_shutdown, so we don't
wedge waiting for the mfs process.
 - in ltsleep, treat ((curproc == NULL) && doing_shutdown) like the
panicstr case.

Appears to fix: kern/9239, kern/10187, kern/9367.
May also fix kern/10122.

Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.

For each leaf filesystem, add appropriate vfs_done routine.

Non 2**n block support is automatic for LKM's and conditional for kernels

Add workaround hacks to enable the softdep code to call getnewvnode()
when a filesystem is being unmounted. The problem is that the softdep
code stored inode numbers in the worklist structures, and does not
use vnodes. So VFS_VGET must be used to get a vnode during the final
flush stages, and this can call getnewvnode(), resulting in
a vfs_busy() + MNT_UNMOUNT hang.

I've tried to make the softdep code use vnodes, but that's a pain,
since it gets called at points were vnode ops are dangerous (i.e.
interrupt context, and uncertainty whether a vnode is locked, etc).

This is all icky stuff, but it does get things much closer to a
working state..

Fix kern/7906: race between unmount and getnewvnode()

mp->mnt_flags & MNT_MWAIT is replaced by mp->mnt_wcnt, and a new mount
flag MNT_GONE is created (reusing the same bit).

In insmntque(), add DIAGNOSTIC check to fail if the filesystem vnode
is being moved to is in the process of being unmounted.

getnewvnode() now protects the list of vnodes active on mp with
vfs_busy()/vfs_unbusy().

To avoid generating spurious errors during a doomed unmount, change
the "wait for unmount to finish" protocol between dounmount() and
vfs_busy().  In vfs_busy(), instead of only sleeping once, sleep until
either MNT_UNMOUNT is clear or MNT_GONE is set; also, maintain a count
of waiters in mp->mnt_wcnt so that dounmount() knows when it's safe to
free mp.

tested by running a "while :; do mount /d1; umount -f /d1; done" loop
against multiple find(1) processes.

Snapshot of work-in-progress, committed to private branch.

These changes implement machine-independent root device and file system
selection.  Notable features:

	- All ports behave in a consistent manner regarding root
	  device selection.
	- No more "options GENERIC"; all kernels have the ability
	  to boot with RB_ASKNAME to select root device and file system
	  type.
	- Root file system type can be wildcarded; a machine-independent
	  function will try all possible file systems for the selected
	  root device until one succeeds.
	- If the root file system fails to mount, the operator will
	  be given the chance to select a new root device and file
	  system type, rather than having the machine simply panic.
	- nfs_mountroot() no longer panics if any part of the NFS
	  mount process fails; it now returns an error, giving the
	  operator a chance to recover.
	- New, more consistent, config(8) grammar.  The constructs:

		config netbsd swap generic
		config netbsd root on nfs

	  have been replaced with:

		config netbsd root on ? type ?
		config netbsd root on ? type nfs

	  Additionally, the operator may select or wildcard root file
	  system type in the kernel configuration file:

		config netbsd root on cd0a type cd9660

	  config(8) now requires that a "root" specification be
	  made.  "root" may be wired down or wildcarded.  "swap" and
	  "dump" specifications are optional, and follow previous
	  semantics.

	- config(8) has a new "file-system" keyword, used to configure
	  file systems into the kernel.  Eventually, this will be used
	  to generate the default vfssw[].

	- "options NFSCLIENT" is obsolete, and is replaced by
	  "file-system NFS".  "options NFSSERVER" still exists, since
	  NFS server support is independent of the NFS file system
	  client.

	- sys/arch/<foo>/<foo>/swapgeneric.c is no longer used, and
	  will be removed; all information is now generated by config(8).

As of this commit, all ports except arm32 have been updated to use
the new setroot().  Only SPARC, i386, and Alpha ports have been
tested at this time.  Port masters should test these changes on their
ports, and report any problems back to me.

More changes are on their way, including RB_ASKNAME support in
nfs_mountroot() (to prompt for server address and path) and, potentially,
the ability to select rarp/bootparam or bootp in nfs_mountroot().

Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

      lookup returned real error on create and rename instead of EJUSTRETURN
      rename changed `.' entry in child instead of name entry in parent
      rename removed `.' entry in child instead of removing entry in
              parent when moving a directory from one dir to another
      createde() left new node locked when write of parent failed (deadlock)
      removede() decremented refcount even on error (rmdir's which failed
              due to write errors left in-core cache entries inconsistent)
      changed validation for filesystem to not check for the boot signature
              since some disks (e.g., mtools) aren't bootable
      directories are always show current time as modify time
              (needed for NFS export since DOS never updates dir mod times --
               ctime is true create time).

 - Added support for cookies changes to the readdir() vnode
      interface (#ifdef __bsdi__)

 - Punted on the whole problem of inode generation numbers.  This means
   that there's a chance of using a stale file handle to access a new
   file, but it doesn't appear to be the common case, and I don't see
   how to generate reasonable generation numbers without changing something
   on the disk (which is the way the SVR4 filesystem survival kit guys
   did it).  I don't think it would be very safe to change the on-disk
   format.
