Hi all, currently _require_loop skips zoned devices, which is a bit odd as loop devices run perfectly fine any file systems. There is one test that runs a loop device on top of a block device, so that is excluded for zoned devices specifically instead. Note that with this zoned btrfs this now fails btrfs/199, which is a bit odd as the test only operates on a loopback file that shouldn't be affected by using a zoned file systems. It would be great if the btrfs folks could try to help me to understand why and either skip it for zoned file systems with a good explanation or skip it.
