In debian/tree/lvm2/lib/udev/rules.d/56-lvm.rules, several internal LVM
names are checked so that they will be skipped for symlinks.  I think that
_mlog (for the mirror log) and -cow & -real (for snapshots) are missing
from the list.

Additionally, is it intentional to create dm-name and dm-uuid symlinks for
these internal devices?  Nothing should be using /dev/disk/by-id to access
them, so I think it makes sense to move the check in
above those symlinks too.
