During the commands: - btrfs filesystem show - btrfs device scan the devices "scanned" are extracted from /proc/partitions. This should avoid to scan devices not suitable for a btrfs filesystem like cdrom and floppy or to scan not existant devices. The old behavior (scan all the block devices under /dev) may be forced passing the "--all-devices" switch.
