Use opendisk when looking for filesystem type, otherwise the detection
only works if the correct device path is given as an argument.

fix logic that handles command line arguments. Now you can:

fsck /mnt/point
fsck dkX
fsck rdkX
fsck /dev/dkX
fsck /dev/rdkX
fsck NAME=wedge

branches: 1.51.10;
use getfsspecname()

branches: 1.50.2;
Use __dead and __printflike.

Dont pass option -x down to fsck_xxxfs.

Hi christos ...

Add -x <mountpoint> ``exclude'' option.

Make sure that the exit values are always sane, and use symbolic instead
of magic constants. Reviewed by go@

kill MFSNAMELEN

Sprinkle volatile, instead of using the (void)&foo; which does not work on
gcc 4.

- add volatile
- static before const

Programs that use efun.

Coverity CID 1745: Fix memory leak.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

Add 'P' (progress meter flag) to getopt()'s optstring, remove
main() prototype.

Sync usage with reality.

When we run with 'fsck -f -n' we should go over all the filesystems, not
exit on the first one that fails. Add a new flag CHECK_NOFIX so that we
specify -n, we keep going.

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

Try the DIOCGWEDGEINFO ioctl first. If that succeeds (i.e. the block
device is a wedge), use the partition type string from the dkwedge_info
structure to get the file system type.

Deal with RESCUEDIR

Replace the statfs() family of system calls with statvfs().
Retain binary compatibility.

Remove my license.

Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

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.

if _PATH_RESCUE is defined, try that before _PATH_SBIN & _PATH_USRSBIN

Sync getopt() / man page with actual getopt options.

fix a couple of -Wshadow warnings

- Don't attempt to fsck a file system that is mounted read-write unless -f
(force) is given. fsck(8) will return with a zero exit status if "fsck -p"
is used in this circumstance, but all other invocations (e.g, "fsck",
"fsck /filesystem", "fsck -p /filesystem") will return with a non-zero exit
status in this circumstance.
Per discussions with various people including Bill Sommerfeld.
- Use "file system" instead of "filesystem"

ansi knf

use TAILQ_xxx instead of referencing tqh_xxx elements directly

convert to use getprogname()

remove redundant declarations and nested externs.

Copy code across from newfs so that 'fsck sd0a' and similar will work.

Adjust for DKTYPENAME changes.

Rewrite catopt(), as in mount(8).

Format police.

PR/4384: Brian Grayson: Use real name for exec'ed child's argv[0]

branches: 1.13.2;
The number of fs types is FSMAXTYPES not DKMAXTYPES.

* cleanup for WARNS=1
* deprecate register
* prefix hex numbers with '0x'

eliminate excess errx() argument

Move fscknames to <sys/disklabel.h> where they belong logically.

PR/3002: bug in my previous commit.

PR/2975: fsck lies to children about their program name
PR/2979: fsck is not smart enough about filesystems not in /etc/fstab

- Null terminate the argv vector [from ws]
- Dynamically allocate the argv vector
- Add -f global flag [from ws]

Fix typo.

Allow for an extra argument needed by quotacheck.

- Rename util.c and util.h to fsutil.c and fsutil.h to avoid conflict with
<util.h>
- Change checkfstab so that the checkit function takes the name of the
mount point too (needed by quotacheck).
- Remove globals debug, verbose and preen

fix up a debugging printf (was given its args in the wrong order), and
allow "ufs" in /etc/fstab to indicate MOUNT_UFS == MOUNT_FFS (for backward
compatibility).

- added -T fstype:fsoptions per cgd's suggestion.
- handle parallelism in preening here using the original preening code from
fsck_ffs.
- move common code from fsck_ffs and fsck_msdos here.

New version of filesystem independent fsck(8) program similar to mount(8).
