s/contigous/contiguous/ in comment.

fix incorrect test

Fix metadata_cksum (Vladimir Serbinenko)

Current code always assumes that CG uses crc16. Yet when metadata_cksum is
enabled then it uses truncated crc32c. This patch doesn't implement full
metadata_cksum, just allows volumes with metadata_cksum to be mounted
read-only.

ext2fs: Nix trailing whitespace.

Support INCOMPAT_64BIT on ext4 (Vladimir 'phcoder' Serbinenko)

update from HEAD

Sync with HEAD

Change ext2fs to use vcache_new like we did for ffs:
- Change ext2fs_valloc to return an inode number.
- Make ext2fs_makeinode private to ext2fs_vnops.c and
  pass vattr instead of mode.

Sync with HEAD

modify the comment to note code needs to brele() to have a shot on actually
working

#if 0 the check for ext2fs_mapsearch() failure (similar what was done
for ffs counterpart), it actually never fails, it panics instead

add support for GDT_CSUM AKA uninit_bg feature

KNF, no functional changes...

Sync with HEAD

support arbitrary ext3/ext4 inode size, add all the new ext4 fields ext2fs_dinode, and add support for loading the extra inode data

Remove the 'cred' argument from bread(). Remove a now unused var in
ffs_snapshot.c. Update the man page accordingly.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

fsbtodb() -> FFS_FSBTODB(), EXT2_FSBTODB(), or MFS_FSBTODB()
dbtofsb() -> FFS_DBTOFSB() or EXT2_DBTOFSB()

Welcome to 6.99.16

PR kern/46282 (6.0_BETA crash: msdosfs_bmap -> pcbmap -> bread -> bio_doread)

Write support for the Ext4 Read-only Compatible Feature "huge_file".

Primarily, this feature extends the inode block count field to 48 bits.
Additionally, this feature allows this field to be represented in file
system block size units rather than DEV_BSIZE units.

Commit is split, to avoid a "too many arguments" protocol error.

Introduce several actions/requests for authorizing file-system related
operations, specifically quota and block allocation from reserved space.

Modify ufs_quotactl() to accomodate passing "mp" earlier by vfs_busy()ing
it a little bit higher.

Mailing list reference:

Note that the umapfs request mentioned in this thread was NOT added as
there is still on-going discussion regarding the proper implementation.

Make sure all cached buffers with valid, not yet written data have been
run through copy-on-write.  Call fscow_run() with valid data where possible.

The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against
endless recursion.

- Add a flag B_MODIFY to bread(), breada() and breadn().  If set the caller
  intends to modify the buffer returned.

- Always run copy-on-write on buffers returned from ffs_balloc().

- Add new function ffs_getblk() that gets a buffer, assigns a new blkno,
  may clear the buffer and runs copy-on-write.  Process possible errors
  from getblk() or fscow_run().  Part of PR kern/38664.

Follow the merge of pmap.c on i386 and amd64 and move

Merge ffs locking & brelse changes from the vmlocking branch.

- 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.

  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

Fix disclaimer in my copyright. Pointed out by Thomas Klausner.

Patches provided by Joel Baker in PR 22364, verified by myself.

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.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

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

* 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.

Bump the kernel rev up to 1.6V

More ufs2 merge fall-out.  Pass the correct pointer to the dinode

Initial commit of recent changes to make DEV_BSIZE go away.

Runs on i386, needs work on other arch's. Main kernel routines should be
fine, but a number of the stand programs need help.

cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512
byte block devices. vnd, raidframe, and lfs need work.

Non 2**n block support is automatic for LKM's and conditional for kernels
on "options NON_PO2_BLOCKS".

Make sure a buffer optained from bread() is always bresle()'d in case of
error. Closes PR kern/1448 from Wolfgang Solfrank.

For consistency w/ FFS/LFS, define EXT2_DINODE_SIZE, and use it instead
of pointer arithmetic and/or sizeof(struct ext2fs_dinode).
