Version-Release number of selected component (if applicable): 3.12 How reproducible: Steps to Reproduce: 1. echo "0 1 zero" | dmsetup create test 2. run in separate window 'udevadm monitor --kernel --env' 3. dmsetup remove test Actual results: KERNEL[74912.993392] remove /devices/virtual/block/dm-8 (block) ACTION=remove DEVNAME=/dev/dm-8 DEVPATH=/devices/virtual/block/dm-8 DEVTYPE=disk DM_COOKIE=6348169 MAJOR=253 MINOR=8 SEQNUM=2279 SUBSYSTEM=block UDEV_LOG=3 KERNEL[74912.994059] remove /devices/virtual/bdi/253:8 (bdi) ACTION=remove DEVPATH=/devices/virtual/bdi/253:8 SEQNUM=2280 SUBSYSTEM=bdi UDEV_LOG=3 KERNEL[74912.994671] remove /devices/virtual/block/dm-8 (block) ACTION=remove DEVNAME=/dev/dm-8 DEVPATH=/devices/virtual/block/dm-8 DEVTYPE=disk MAJOR=253 MINOR=8 SEQNUM=2281 SUBSYSTEM=block UDEV_LOG=3 Expected results: Only 1 remove event for dm-8 Additional info:
