cramfs is an endianness dependent file system. So far, the cramfs
utilities did not support cramfs images of different endianness than
the host machine.
A separate utility, cramfsswap, was required in order to change the
endianness of the image before and after using cramfs utilities. The
extra utility introduced extra maintenance and an additional step in
the process.
This patch adds endianness support to mkfs.cramfs and fsck.cramfs.
fsck.cramfs now automatically detects the image endianness, and can
work on images of either endianness. mkfs.cramfs now accepts a new
optional parameter (-N) that allows creating the cramfs image in
either endianness.

The mount command does not work properly if you replace suid with
POSIX file capabilities. We still need to check for non-root mounts and
the command has to work in very restricted mode for non-root users.
This patch allows you to remove suid bit from mount and umount. Note
that you need a system with filesystem capability support, e.g.
Fedora 10).
# ls -l /bin/mount
-rwxr-xr-x 1 root root 65192 2008-11-09 22:59 /bin/mount
# getcap /bin/mount
/bin/mount = cap_dac_override,cap_sys_admin+ep
[kzak@redhat.com: all the above comments]
Don't bypass security checks when [u]mount uses POSIX file capabilities
rather than setuid root to permit non-root mounts.

People usually want to use pm-utils to suspend the system instead of
the raw kernel interface, so I added an option to just exit after
configuring the wakeup time.
Actually I think that all the suspend code should be removed from
rtcwake, since it does not really belong there.

We practically have three io scheduling classes. The "none" is
de facto "best-effort" class for processes that has not asked
for io priority.

Support for multiple instances of devpts were included in 2.6.29-rc1.
Update man pages to document the new options. Additional details about
the new options are described in 'Documentation/filesystems/devpts.txt'
of kernel source tree.

fix:
- don't call canonicalize_spec() for LABELs/UUIDs
- simplify the code
- rename to getfs_by_devdir(), because we use it only for
device names and not for SPECes (see umount.c).

The [u]mount does not properly support LABEL="foo" or UUID="foo" in
/etc/fstab. This patch fix last places where we assume unquoted
LABELs/UUIDs only.

The raw devices are in the raw/ subdirectory. It makes sense to use
the same subdirectory also for the control file. The old /dev/rawctl
is also supported as a fallback.
The #ifdef OLD_RAW_DEVS (/dev/raw<N>) is unsupported from now.

The SPEC (fsname) field in fstab/mtab could be:
- devname
- NAME=value (e.g LABEL, UUID)
- directory (MS_MOVE, MS_BIND, ..)
- pseudo-fs keyword (tmpfs, proc, sysfs, ...)
the pseudo-fs keywords shouldn't be canonicalized to absolute path. It
means we have to differ between SPEC and mountpoint (fs_dir).
Unfortunately, the keywords was checked on wrong place. This patch
move this check to the new function canonicalize_spec().
The fsname in mtab entry is canonicalized when the FS type is not
pseudo filesystem.

As swap format depends on the pagesize being used, it may happen
that the pagesize of the swap space and the current pagesize differ,
resulting in swapon to fail when trying to enable such a swap space.
In such a case swapon should rather reinitialize the swap space.
[kzak@redhat.com: - add blkdev.c to the global swapon_SOURCES
- don't try to detect for huge pages on small swap
areas (or when read() returns less than MAX_PAGESIZE)
- fix fprintf() format string]

With this patch, you can lock directory. Additionally,
lockfile opens with O_NOCTTY.
Try to open file with O_CREAT flag first, and without it
if open fails with EISDIR. Suggested by H. Peter Anvin.
