vdev_id uses the /dev/mapper/ symlinks to resolve a UUID to a dm name (like dm-1). However on some multipath setups, there is no /dev/mapper/ entry for the UUID at the time vdev_id is called by udev. However, this isn't necessarily needed, as we may be able to resolve the dm name from the $DEVNAME that udev passes us (like DEVNAME="/dev/dm-1"). This patch tries to resolve the dm name from $DEVNAME first, before falling back to looking in /dev/mapper/. This fixed an issue where the by-vdev names weren't reliably showing up on one of our nodes.
