Subject: [PATCH v2 2/3] btrfs/146: Add _require_scratch_dev_pool before _require_dm_target
Date: Wed,  8 Sep 2021 17:37:14 +0900	[thread overview]
Message-ID: <20210908083715.1831067-3-shinichiro.kawasaki@wdc.com> (raw)
In-Reply-To: <20210908083715.1831067-1-shinichiro.kawasaki@wdc.com>

The test case btrfs/146 calls _require_dm_target which depends on
SCRATCH_DEV. The test case assumes that valid devices are set in
SCRATCH_DEV_POOL, and one of the devices is propagated to SCRATCH_DEV.
However, when SCRATCH_DEV_POOL is not set, valid value is not propagated
to SCRATCH_DEV and _require_dm_target causes unexpected test case
failure. To avoid the failure, add _require_scratch_dev_pool call before
_require_dm_target call to detect invalid SCRATCH_DEV_POOL beforehand.

Of note is that the test case replaces SCRATCH_DEV_POOL value internally
and calls _require_scratch_dev_pool for the replaced SCRATCH_DEV_POOL.
With this fix, the test case will call _require_scratch_dev_pool twice
for the original SCRATCH_DEV_POOL and the replaced SCRATCH_DEV_POOL.
