Restore backward compatibility of UFS2 with previous NetBSD releases by
disabling support in UFS2 for extended attributes (including ACLs).
Add a new variant of UFS2 called "UFS2ea" that does support extended attributes.
Add new	fsck_ffs operations "-c	ea" and	"-c no-ea" to convert file systems
from UFS2 to UFS2ea and	vice-versa (both of which delete all existing extended
attributes in the process).

Sync with HEAD

Add a -z flag to zero out the up to 4 bytes of padding in directory entry
names (including the terminating NUL), as well as directory entries with
extra free space (d->d_reclen > UFS_DIRSIZ(d)).

Inspired from FreeBSD:
    https://svnweb.freebsd.org/base?view=revision&revision=347066

While the kernel has been fixed to deal with the padding bytes (new
kernels will correctly zero out all the padding after the name), it
appears that there is still an issue with directory entries with extra
free space, since a newly created and populated filesystem gets modified
with "fsck_ffs -z".

Document the version fsck_ffs first appeared.
Bump date.

Mention scan_ffs -b.
Based on a patch by Matthew Mondor <mm_lists@pulsar-zone.net> on
tech-userlevel.
Bump date.

Improve documentation of FFS formats and format levels from PR 32100.
Prompted also by recent discussion on tech-kern. Bump date.

Re-add -q description that got lost when -x was added.
Sort descriptions.
Bump date.

Sync with HEAD.

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

New sentence, new line.

Use "FFSv2" instead of "UFS2".
Expand the description of -c.

Disable userid to username lookups by default. Add a -U flag to perform them.
In single user mode lookups that involve the network might not work and they
slow down fsck.

Add an explanation of why one would want to use -x/-X, after
discussion with bouyer@.

Add fss(4) snapshot support to fsck_ffs(8) (via -x or -X options, like
dump(8)). This allows fsck_ffs -n to work on a snapshot of a R/W mounted
filesystem, and avoid errors related to filesystem activity.

Merge the simonb-wapbl branch.  From the original branch commit:

   Add Wasabi System's WAPBL (Write Ahead Physical Block Logging)
   journaling code.  Originally written by Darrin B. Jewell while
   at Wasabi and updated to -current by Antti Kantee, Andy Doran,
   Greg Oster and Simon Burge.

OK'd by core@, releng@.

Add support for creating a WAPBL log in the filesystem.  Will
create an in-filesystem log on first "mount -o log" if one doesn't
exist, and will then continue to use same log in the future.  See
(soon to be added) wapbl(4) for more info.

Adds a new B_CONTIG low-level allocation flag that uses hints in
"struct ffs_inode_ext" to lay out an ffs file's data contiguously.

Thanks to Greg Oster for helping with the design of this and to
Antti Kantee for code review and suggestions.

Sort options. Bump date for -P. Remove superfluous -.

Add a progress meter to fsck_ffs based on the work by thorpej presented
to the mailing lists last January. This is optional.

Pull up revision 1.38 (via patch) (requested by fair in ticket #435).

Correct a misnumbering of options, as noted in PR 25784.

Correct a misnumbering of options, as noted in PR 25784.

Various improvements; mostly mention arguments of flags by name to
simplify the description and improve lists.

Update Dd for previous and fix a case.

do not upgrade superblock or set FS_FLAGS_UPDATED unless -c 4 option
is provided.
add compatibility for filesystems before FFSv2 integration
these patches are from pr port-macppc/23925 and should also
fix problems discussed in pr kern/21404 and pr kern/21283

Add a -q (quiet) option to print nothing for clean filesystems.
Support in fsck_ffs and stub in fsck_xxx.
Push a few more messages through pwarn() instead of printf() to ensure
disk name is shown.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22308, verified by myself.

.Nm does not need a dummy argument ("") before punctuation or
for correct formatting of the SYNOPSIS any longer.

New sentence, new line. By Robert Elz with minimal fixes.

Add support for the Apple UFS variation on ffs
This is the bulk of PR #17345

The general approach is to use a run time deteriminable value
for DIRBLKSIZ.  Additional allowances are included for using
MAXSYMLINKLEN with FS_42INODEFMT and a shift in the cylinder group
cluster summary count array.  Support is added for managing
the Apple UFS volume label.

If SIGINFO is received, display summary information to stderr.

Edit -mdoc usage.

* There is no -indent option to .Bd or .Bl, although you would
  never know that from its frequent use in this tree. There is a
  "-offset indent" combination that makes sense, and you can certainly
  say "-width indent".

* Also, you can't markup the -width option argument, tho you CAN
  use a callable macro. So "-width Ar filename" doesn't make sense,
  but either "-width Ar" or "-width filename" does, as might something
  like "-width xxfilename" for a little extra space.

* There are a lot of needlessly complex hanging tag macros in man4 used
  to create simple item lists. Those should be simplified one of these
  days before someone copies and edits yet another man4 page.

Sort SEE ALSO, whitespace nits.

- changes to -F semantics:
	- remove the restriction that filesystem must be a regular file
	- don't try and read a disklabel
- use `p' (instead of `h') as the index of the last partition

- implement -F; treat provided filesystems as images in regular files
- replace "filesystem" with "file system" as appropriate
- grammar fixes

Drop arguments of .Os.

Clean up SYNOPSIS formatting.

fix typo.

Add support for non-native byteorder FFS, and converting byteorder.
Also, be a bit more conservative with the clean flag: don't mark the FS
clean when we know there may still be errors (user anserwed 'n' to
a question, or fsck says "you must rerun fsck").

use .Nm correctly

* cleanup for WARNS=1
* deprecate register
* cleanup manpage
* remove unused docheck() func
* prefix hex numbers with '0x'
* getopt returns -1 not EOF

lost+found directories are mode -1700

The fs level (ref: fsck -c ...) can be determined from the second
line of the output from dumpfs(8), not the first line. part of [bin/1353]

fix reboot(8) xref

eliminate obsolete references to mkfs(8);
from Klaus Klein <kleink@layla.inka.de>

Update this to reflect reality after the fsck/fsck_ffs split.

- fixed all printf formats [there were a lot of %l? <-> %? mistakes]
- added missing prototypes, and made local functions static
- removed parallel preening code; this is part of fsck(8)
- use printing utilities from fsck(8)
- Makefile does not make links to fsck and fsck.8
- removed -l maxparallel option. It has no meaning anymore.

check in changes proposed in PR 2006 (approved by J.T.), to rename fsck
to fsck_ffs, so that in the future 'fsck' can be a wrapper than invokes
appropriate filesystem-specific checker programs.  For now, the only
user-visible change is that the names have changed in the manual page
and in error messages; fsck and fsck.8 are now links to fsck_ffs and
fsck_ffs.8, until the rest of the transition is complete.

implement a 'force check' flag, '-f'.  I used the SunOS name, but the Digital
semantics.  now:
	(1) dirty file systems will always be checked; nothing new there.
	(2) if not '-f' clean file systems will _NEVER_ be checked,
		i.e. they won't be checked even if -p isn't specified.  This
		allows one to 'fsck -p ; fsck' to preen, then clean up
		anything that 'fsck -p' barfs on, without waiting for the
		clean file systems to be checked again.
	(3) if '-f' clean file systems will ALWAYS be checked.  This
		allows people to put 'fsck -fp' into /etc/rc on systems
		where they're leery of the FS clean flag state, need
		the extra reliability, and can afford time 'wasted'
		in checks.
The assumption made here is that if a file system is marked clean, it
_IS CLEAN_, really, and shouldn't be checked unless fsck is explicitly
told to (with -f).  This should be a valid assumption, but may not be in
the presence of file system bugs.  Documentation updated to note '-f'.
