[PATCH] btrfs: kobject_uevent should use bd_part instead of bd_disk
which should fix. Could you try and update.
Thanks, Anand

Btrfs will send uevent to udev inform the device change,
but ctime/mtime for the block device inode is not udpated, which cause
libblkid used by btrfs-progs unable to detect device change and use old
cache, causing 'btrfs dev scan; btrfs dev rmove; btrfs dev scan' give an
error message.
