sigh. If udev rule set this flag, it is not top-level device
and nobody should touch it.

Top level device is then visible, that's the one you want to mount...

if you see the log, event comes there for top-level:

04:04:20.064 [D] osspec.c:249: Found a dm-device (/dev/dm-6), mark it
04:04:20.064 [I] osspec.c:256: SEQNUM"50, ACTION=change, SUBSYSTEM=block, DEVPATH=/sys/devices/virtual/block/dm-6, DEVNAME=/dev/dm-6, IFINDEX=0

so I do not think it is problem with this patch.

But in fact I have no idea how the whole desktop machinery above
that works, I expect that there is some race with another auto mount
system - see dmsetup table if the device is not mapped elsewhere already:-)
