The LOOP_SET_CAPACITY allows to resize loop device size.
Example:
# blockdev --getsize64 /dev/loop0
10485760
# dd if=/dev/zero of=/home/images/aaa.img count=10 bs=1M oflag=append conv=notrunc
# blockdev --getsize64 /dev/loop0
10485760
# ./losetup --set-capacity /dev/loop0
# blockdev --getsize64 /dev/loop0

This patch allows to detach more devices by "losetup -d",
for example:
# losetup -a
/dev/loop0: [0804]:9955739 (/home/images/ary0.img)
/dev/loop1: [0804]:9955740 (/home/images/ary1.img)
/dev/loop2: [0804]:9955745 (/home/images/ary2.img)
# losetup -d /dev/loop0 /dev/loop1 /dev/loop2

losetup -j | --associated <file> [-o <num>]
This new option lists all loop devices associated with given file
(and optionally file offset).
Examples:
# losetup -a
/dev/loop0: [0807]:21921808 (/foo/vfat-mbr.img)
/dev/loop1: [0807]:21921808 (/foo/vfat-mbr.img), offset 100
/dev/loop2: [0807]:21921802 (/bar/ext3.img)
# losetup -j /foo/vfat-mbr.img
/dev/loop0: [0807]:21921808 (/foo/vfat-mbr.img)
/dev/loop1: [0807]:21921808 (/foo/vfat-mbr.img), offset 100
# losetup -j /foo/vfat-mbr.img -o 100
/dev/loop1: [0807]:21921808 (/foo/vfat-mbr.img), offset 100

The losetup provides an -f option to discover an unused loop device. As
implemented, it is racy. The problem is that -f prints the loop device
to stdout only when used standalone. This means a script has to do:
lodev=$(losetup -f)
losetup $lodev $filename
which is racy if another script may be running.
This patch add a new option '-s'. The '-s' option prints device name
if the -f option and a file argument are present. For example:
lodev=$(losetup -f -s $filename)

This feature has been already supported by mount, but it wasn't accessible by
losetup command. Now you can use "losetup -r".
