small bug in mkfs.cramfs + patch
mkfs.cramfs on version v2.17.2 has a small bug when dealing with very small
filesystems. look at upstream code on git, and the issue is still here.
ex:
$ cd /tmp
$ mkdir content
$ echo hello > content/a
$ echo hello > content/b
$ mkfs.cramfs content content.cramfs
not enough space allocated for ROM image (4090 allocated, 4096 used)
Here is a patch for fixing (simply rounding to page size AFTER eleminating
doubles).

fallocate: add FALLOC_FL_PUNCH_HOLE support
Recent Linux kernel supports FALLOC_FL_PUNCH_HOLE in fallocate(2).
This patch adds FALLOC_FL_PUNCH_HOLE support to fallocate utility,
by introducing a new option -p|--punch-hole.

prlimit: add support for executing a command
prlimit.c: Alternatively to applying the limits to an existing process via the
--pid option, allow a command to be executed. Adapted usage() accordingly.
prlimit.1: mention new syntax.

The lock file cannot be opened in read-write mode by default, because
then we cannot use flock(1) to lock executable files.
The read-write mode for lock files is necessary on NFSv4 where
flock(2) is emulated by by fcntl() -- this situation is possible to
detect by flock(2) EIO error.
This patch reverts the default to O_RDONLY and use O_RDWR only if EIO
error is detected.

prlimit: fix case when PID is given later
# prlimit --nofile=:4000 --pid $$
When the PID is given later than a partially given limit, then prlimit
used the current PID for getting the missing part (hard, soft) of the
limit.
Factored out the retrieval of the unknown limit from parse_prlim() to
new get_unknown_hardsoft() which is to be called by do_prlimit() based
on the struct prlimit member 'modify' set by add_prlim().

- add soft vs. hard limit check from another

prlimit: fix error message
- differentiate between set and get operations
- add limit name to the error message
- remove PID from the message (whole util works always with only one
PID, so this info is superfluous)

prlimit: show all limits if called without options
Fix option parsing: prlimit ran into usage() if called
without arguments which should only be done for surplus
arguments. Instead, it should display all limits.

fdisk: split delete_partition() off from dos_delete_partition()
This accidentally fixes a mistake printing the "Partition n is deleted"

logical partitions.

This allows the creation of a new label if the disk already has an existing
SGI disklabel without working around this problem such as creating a DOS
disklabel or overwriting with zero the partition table (problem reported in
'Gentoo Linux/MIPS Handbook').

wipefs: improve -a, use blkid_do_wipe()

example if a magic string is stored on more places on the device. The
current implementation always removes from the device only the firstly
