Version 1.02.04 -
============================
Bring dmsetup man page up-to-date.
Use name-based device refs if kernel doesn't support device number refs.
Fix memory leak (struct dm_ioctl) when struct dm_task is reused.
If _create_and_load_v4 fails part way through, revert the creation.

List device names. Optionally only list devices that have at least
one target of the specified type. Optionally execute a command for
each device. The device name is appended to the supplied command.
--tree displays dependencies between devices as a tree.
It accepts a comma-separate list of options.
Some specify the information displayed against each node:
device/nodevice; active, open, rw, uuid.
Others specify how the tree is displayed:
ascii, utf, vt100; compact, inverted, notrunc.

Suspends a device. Any I/O that has already been mapped by the device
but has not yet completed will be flushed. Any further I/O to that
device will be postponed for as long as the device is suspended.
If there's a filesystem on the device which supports the operation,
an attempt will be made to sync it first unless --nolockfs is specified.
