I believe the patch needs to go in different direction.
See the bug https://bugzilla.redhat.com/show_bug.cgi?id=905028
Lvm2 should be smarter in it's scanning code and
must avoid reading device it know it may block.
There are very similar problems i.e. with thin pools, so
it's not practical to put in various hacks for individual
targets.
The fix must be in the filter to skip known dm devices.
