[PATCH v2 0/8] fstests: add checks for testing zoned btrfs

[Naohiro Aota <naohiro.aota@wdc.com>]

This series revisit my old series to test zoned btrfs [1].

[1] https://lore.kernel.org/fstests/PH0PR04MB7416870032582BC2A8FC5AD99B299@PH0PR04MB7416.namprd04.prod.outlook.com/T/

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 4 handle the too small file system failure.

And, patches 5 to 8 add checks for tests requiring non-zoned devices.

Naohiro Aota (8):
  common/rc: introduce minimal fs size check
  common/rc: fix blocksize detection for btrfs
  btrfs/057: use _scratch_mkfs_sized to set filesystem size
  fstests: btrfs: add minimal file system size check
  common: add zoned block device checks
  shared/032: add check for zoned block device
  fstests: btrfs: add checks for zoned block device
  fstests: generic: add checks for zoned block device
