We already have /dev/disk/by-id/dm-uuid-... (which encompasses the VG UUID and LV UUID in case of LVs since the mapping's UUID is VG+LV UUID together) and /dev/disk/by-id/dm-name-... (which encompasses the VG and LV name in case of LVs). This patch addds /dev/disk/by-id/lvm-pv-uuid-<PV_UUID> that completes this scheme and makes navigation a bit easier using PV UUIDs since one can navigate using PV UUIDs only and there's no need to do extra PV UUID <--> kernel name matching (the PV UUID is stable across reboots). This may come in handy in various scripts. Since we already have the PV UUID stored in udev database (as a result of blkid call - returned in ID_FS_UUID blkid's variable), this operation is very cheap indeed, just creating the extra one symlink.
