If called without -T or -t, fsck attempts to detect the
file system type. If this fails, fsck will fail with
"unknown file system type" message.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Add the '-C' "check clean" flag. If the FS is marked clean, skip file
system checking. However, if the file system is not clean, perform a
full fsck.

mdoc(7) police: update document date, sort xrefs, fix markup.

Add support for running foreground (-F) and background (-B) checks.
Traditionally, fsck is invoked before the filesystems are mounted
and all checks are done to completion at that time. If background
checking is available, fsck is invoked twice. It is first invoked
at the traditional time, before the filesystems are mounted, with
the -F flag to do checking on all the filesystems that cannot do
background checking. It is then invoked a second time, after the
system has completed going multiuser, with the -B flag to do checking
on all the filesystems that can do background checking. Unlike
the foreground checking, the background checking is started
asynchonously so that other system activity can proceed even on
the filesystems that are being checked.

At the moment, only the fast filesystem supports background checking.
To be able to do background checking, a filesystem must have been
running with soft updates, not have been marked as needing a
foreground check, and be mounted and writable when the background
check is to be done (i.e., not listed as `noauto' in /etc/fstab).

These changes are the final piece needed to support background
filesystem checking. They will not have any effect until you update
your /etc/rc to invoke fsck in its new mode of operation. I am
still playing around with exactly what those changes should be
and should be committing them later this week.

mdoc(7) police: use .Nm instead of hardcoded name.

This change sanitizes the way fsck deals with pass numbers.

Consider this /etc/fstab:

# Device Mountpoint FStype Options Dump Pass#
/dev/ad1s1b none swap sw 0 0
/dev/ad0s1b none swap sw 0 0
/dev/ad0s1a / ufs rw 1 1
/dev/ad0s1e /home ufs rw 2 2
/dev/ad1s1e /tmp ufs rw 2 2
/dev/ad1s1f /usr ufs rw 2 2
/dev/ccd0c /syv ufs rw 2 11
proc /proc procfs rw 0 0

ccd0c is striped over /dev/ad0f and /dev/ad1g

Without this pass, fsck in preen mode will check ad0s1a first,
and then issue three processes in parallel:

One process doing ad0s1e
One process doing ad1s1e and ad1s1f
One process doing ccd0c

There is no way to tell it that ccd0c overlaps ad0 and ad1.

With the patch, it will do it this way:

pass 2:
One process doing ad0s1e
One process doing ad1s1e and ad1s1f

and when they are complete:

pass 11:
One process doing ccd0c

This is much faster and more sane.

Valid pass numbers are anything from 1 to INTMAX-1.

I retired the '-l' option which tried to allow people to do
something like this, but which didn't work and which complicated
the code an awful lot.

mdoc(7) police: split punctuation characters + misc fixes.

When trying to deduce the diskname from the name so we can run
parallel fsck's one per drive, use the shortest prefix ending in
a digit rather than the longest prefix ending in a digit.

This makes "/dev/ad0s1a" and "/dev/ad0s2a" appear to both reside
on the disk "/dev/ad0" and consequently they will be fsck'ed
sequentially rather than in parallel as now.

In general this heuristic is rather soft and errorprone. For
instance ccd may often reside on two or more physical disks. A
good solution would be to look for passes larger than 1 until no
disks are found in a particular pass, that way people could put
ccd stripes in pass 3... and have them fsck'ed sequentially.

Second part of the fsck wrappers commit. This commit enables the new fsck
code (removing the fsck/* code and replacing it with the netbsd fsck
wrapper code), and enabling some FFS-based utilities to compile.

Details:

* quotacheck, fsdb required modification to use the fsck_ffs/ code rather
than fsck/ . This might change later since quotacheck requires preen.c
which should exist in fsck/ rather than fsck_ffs/

* src/Makefile has fsck_ffs added to it so it it built as part of the tree
now

* share/doc/smm/03.fsck/ uses the SMM.doc/ stuff from fsck_ffs, not fsck.

I've tested this, and it shouldn't require any changes on your machine.
The fsck wrapper reads /etc/fsck and is command-line-compatible enough
to not require rc changes (well, most changes unless you want to do
anything nifty by specifying the fs types explicityly, read the man page
if you want further details on what it can do.)

This now allows us to support multiple filesystem types during bootup.

This exactly matches Kirks sources imported under the
Tag MCKUSICK2. These are as supplied by kirk with one small
change needed to compile under freeBSD.

Some FreeBSD patches will be added back, though many have been
added to Kirk's sources already.

Latest version of fsck from the folks at EX-CSRG specifically Kirk Mckusick.
Don Lewis and Kirk have merges nearly all FreeBSD Fixes into Kirks sources
so there is very little that needs to be re-merged.

Correct use of .Nm. Add rcsid. Remove unused #includes. Use err(3).

Restored lost reference to fsdb(8).

Fixed weird quoting of $Id$.

Merge from Lite2. Note that Lite2 has it's own filesystem clean check
skipping code that overrides ours sooner. One should be eliminated,
but for now it works.

Boy, I'm glad we're not using sup anymore. This update would have been

Remove reference to fsdb(8). We don't have it.

Added filesystem clean bit support. This only affects fsck during a
preen (-p), and in that case the filesystem is skipped if it is clean.
A new flag "-f" for 'force' has been added which basically gives back
the old behavior of checking all the filesystems all the time. This
very closely models the behavior of SunOS and Ultrix.
