[lvm-devel] [PATCH 04/24] Move add_dev_node to DM_DEVICE_RESUME

[Zdenek Kabelac]

This patch came out from discussion with Petr.
We need valid 'check_udev' for stacked ops processing.

Current code:

dmsetup create xxx --notable   ->  create node in /dev/mapper/xxx

(check_udev has incorrect 0 value)

**

New patched code creates node with:

dmsetup resume xxx

(As just at this moment udev is registering such device)
