It was introduced because btrfs used to do blkdev_put in a deferred work, now that btrfs has blkdev_put in place, this rcu_barrier can be removed. modprobe -r btrfs will do btrfs_cleanup_fs_uuids(), where it cleanup every %fs_devices on the list, but when we do btrfs_close_devices(), we have replaced the devices on the list with dummy ones which only have the same name and uuid, so modprobe -r btrfs will free those instead of what we were using, this change won't cause a problem for it.
