btrfs: wake up transaction thread from SYNC_FS ioctl The transaction thread may want to do more work, namely it pokes the cleaner ktread that will start processing uncleaned subvols. This can be triggered by user via the 'btrfs fi sync' command, otherwise there was a delay up to 30 seconds before the cleaner started to clean old snapshots.
