There's no need for foreign udev rules to touch LVM reserved devices (snapshot, pvmove, _mlog, _mimage, _vorigin) even if they happen to be visible. The same applies for /dev/disk content - no need to create any content for these devices (and so no need to run any "blkid" etc.). This also prevents setting any inotify "watch" from udev rules on such devices that is a source of race conditions (the rules need to honor DM_UDEV_DISABLE_OTHER_RULES_FLAG for this to work though).
