got wrong at some time...

42e07d2bce dmsetup: Support remove --deferred.
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.

3cb2658fb7 dmsetup: add warning
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...

Any documentation less-detailed than Documentation/device-mapper is
dangerous for the non-trivial ctr lines.  And anyway, this should be in s4

880507498a Add --addnodeonresume, --addnodeoncreate
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.
