This patch adds a new flag --deferred to dmsetup remove. If this flag is
specified and the device is open, it is scheduled to be deleted on
close.
struct dm_info is extended.
The existing dm_task_get_info() is converted into a wrapper around the
new version dm_task_get_info_with_deferred_remove() so existing binaries
can still use the old smaller structure.
Recompiled code will pick up the new larger structure.

More updates to manglename option.
Add reference to LVM2 resource page, since for a long time,
this is the right places for sources for libdevmapper....
Warn when --udevcookie/DM_UDEV_COOKIE is used with 'dmsetup remove --force'.
When command is doing multiple ioctl operations on a single device,
it may invoke udev activity, that is colliding with further ioctl commands.
The result of such operation becomes unpredictable.
Use of --retry could partially help...
Add 'blkdevname' and 'blkdevs_used' field to dmsetup info -c -o.
Add 'blkdevname' option to dmsetup ls --tree to see block device names.
Add '-o options' to dmsetup deps and ls to select device name type on output.
Any documentation less-detailed than Documentation/device-mapper is
dangerous for the non-trivial ctr lines. And anyway, this should be in s4
not here.
Use standard manpage style.
Keep options and commands in alphabetic order.
Added at least a very simply info about some other targets.
TODO: documenting targest needs far more work...
Add new function dm_task_set_add_node() to select between 2 types
of node creation in device directory.
DM_ADD_NODE_ON_RESUME is now default and ensures node is created on
resume. Old original behavior is accessible with DM_ADD_NODE_ON_CREATE.
In this case node would be created during dmsetup create --notable.
For the user 2 new options for dmsetup create are added:
[{--addnodeonresume | --addnodeoncreate }]
Properly working node creation on resume is needed for proper operation
stacking and ability to correctly check in which state the device should
after whole udev transation.
* dmsetup/dmsetup.c (DEV_PATH): Remove definition.
(parse_loop_device_name): Add parameter: dev_dir.
Declare the "dev" parameter to be "const".
Use dev_dir, not DEV_PATH. Handle the case in which dev_dir
does not end in a "/".
(_get_abspath): Declare "path" parameter "const", to match.
(_process_losetup_switches): Add parameter: dev_dir.
Pass dev_dir to parse_loop_device_name.
(_process_switches): Add parameter: dev_dir.
Pass dev_dir to _process_losetup_switches.
(main): Set dev_dir from the DM_DEV_DIR envvar, else to "/dev".
Call dm_set_dev_dir.
* lib/libdm-common.c (dm_set_dev_dir): Rewrite to be careful
about boundary conditions, now that dev_dir may be tainted.
* man/dmsetup.8: Mention $DM_DEV_DIR.
