This feature allows to call multiple independent fsck instances rather
than use only one "fsck -A" process.
The lock uses LOCK_EX flock(2). The lock request is ignored if the
whole-disk is non-rotating disk. The verbose mode (-V) provides
information about disk locking.
Note that "fsck -l" does not care if the device is stacked, for
example if you want to call "fsck -l /dev/md0" and "fsck -l /dev/md1"
then the underlying devices will not be locked. The traditional "fsck
-A" does not run in parallel for stacked devices.

The brutal force /dev directory scanning should be used as a fallback
solution only. Currently, almost all systems use udev and we can read the
name from /sys/block/<maj>:<min> symlink.

This option is already supported by mount(8) and fsck(8), there is no
reason to have any exception for swap devices. Note that the --ifexists
command line option applies to all swap devices, the "nofail" setting
is per device.

umount(8) segfaults when update incomplete mtab file after remount to
read-only (-r). For example autofs does not store info about
mountpoint to /etc/mtab file.
# mount /dev/sda1 /mnt/test
# sed -i -e 's:/dev/sda1 .*::g' /etc/mtab
# cd /mnt/test
# umount -r /mnt/test
umount: /mnt/test busy - remounted read-only
Segmentation fault
The command "umount -r" should not care about /etc/mtab if the related
mtab entry does not exist.

For the last line of the file lenght of line should be determined
where the EOF is instead of new line. Old output was
$ printf "1 2\n3" | column -t
column: line too long
1 2
which this commit will change to
$ printf "1 2\n3" | column -t

- move all FAT code to superblocks/vfat.c only
- add a generic function to verify FAT superblock and use it
in FAT prober as well as in MBR parser
- add a more robust FAT cluster_count check
(it seems that iPod contains an "almost valid" FAT superblock before MBR)

The example in the man page does not prevent concurrent execution, as it
obtains a shared lock. More useful is taking an exclusive lock, i.e.
remove "-s".
Additionally, IMO most people want the script to exit when the lock
cannot be acquired, so adding "-n".
errno is saved into a local variable to avoid it getting trampled
by perror before it is checked to determine the return value.
This issue seems quite rare, but I have seen it when running sfdisk
via gksudo and using the --quiet command-line option. From what I
can tell, this combination triggers loading of translations in perror,
which (at least on my machine) ends up changing the value of errno.

Old implementation of namei listed path all the way to non-existing
file or directory, something like:
f: /usr/bin/nxdir/file
d /
d usr
d bin
? nxdir - No such file or directory (2)
whiles the current implementation prints:
namei: failed to stat: /usr/bin/nxdir/file: No such file or directory
The new output it's not helpful. I am especially interested see where
the path is broken when a path is symlink to other path with symlink,
and few more like that, and something somewhere is broken.
