Btrfs: add DEVICE_READY ioctl This will be used in conjunction with btrfs device ready <dev>. This is needed for initrd's to have a nice and lightweight way to tell if all of the devices needed for a file system are in the cache currently. This keeps them from having to do mount+sleep loops waiting for devices to show up. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
