[lvm-devel] [PATCH 4/9] Udev integration: add cookie support for dmsetup

[Peter Rajnoha]

...Milan has added some lines to pvmove test recently. But it fails
with udev patches -- it waits for notification which will never come.
We can't wait wait for notification when dmsetup's "--notable"
is set while creating devices -- there's no uevent for this to unlock
the wait :)

So this should be applied on top of the patch "4/9 add cookie support
for dmsetup":
