Several tests are failing on zoned btrfs, but actually they are
invalid. There are two reasons of the failures. One is creating too
small filesystem. Since zoned btrfs needs at lease 5 zones (= 1.25 GB
if zone size = 256MB) to create a filesystem, tests creating e.g., 1
GB filesystem will fail.

The other reason is lacking of zone support of some dm targets and
loop device. So, they need to skip the test if the testing device is
zoned.

Patches 1 to 3 handle the too small file system failure.

And, patches 4 and 5 add checks for tests requiring non-zoned devices.

Naohiro Aota (5):
  common/rc: introduce minimal fs size check
  btrfs/057: use _scratch_mkfs_sized to set filesystem size
  btrfs: add minimal file system size check
  common: add zoned block device checks
  shared/032: add check for zoned block device
