PATCH 1/1 generic _require_dm_target() helper, use in generic/085

generic/085 was failing on a machine w/o devicemapper kernel support because it requires the linear target, but didn't explicitly test for it.

I could have cut & pasted _require_dm_linear(), but chose to go the route of a generic helper, _require_dm_target $FOO, because some day someone will need the zero target, the error target, or who knows.

The first 2 files below are functional changes, creating the helper & using it in generic/085; the rest are just perl edit-in-place changes to use the new generic helper.

PATCH v2 1/1 generic _require_dm_target() helper, use in generic/085

generic/085 was failing on a machine w/o devicemapper kernel support because it requires the linear target, but didn't explicitly test for it.

The first 2 files below are functional changes, creating the helper & using it in generic/085; the rest are just perl edit-in-place changes to use the new generic helper.

V2: assign _target using actual bash syntax! o_O
combine dmsetup stdout & stderr for target grep modprobe the target we're looking for
define cleanup_dmdev() before we _notrun, trap, and try to run it

generic/085 was failing on a machine w/o devicemapper kernel support because it requires the linear target, but didn't explicitly test for it.
I could have cut & pasted _require_dm_linear(), but chose to go the route of a generic helper, _require_dm_target $FOO, because some day someone will need the zero target, the error target, or who knows.

Quoted 6 lines

The first 2 files below are functional changes, creating the helper & using it in generic/085; the rest are just perl edit-in-place changes to use the new generic helper.
Reported-by Angelo Dureghello <[email protected]>
Signed-off-by Eric Sandeen <[email protected]>

Looks good to me overall, generic/085 runs without problems and other affected tests are good too (I only tested generic/034).

Perhaps _dmerror_required() can be removed too, and update btrfs/100 and btrfs/101 to use the new helper?

And there's a trailing whitespace issue, see below

PATCH v3 1/1 generic _require_dm_target() helper, use in generic/085

In reply to Eric Sandeen

generic/085 was failing on a machine w/o devicemapper kernel support because it requires the linear target, but didn't explicitly test for it.

Add the helper, use it in test generic/085, and convert _require_dm_flakey, _require_dm_snapshot, and _dmerror_required with this new helper.

generic/085 was failing on a machine w/o devicemapper kernel support because it requires the linear target, but didn't explicitly test for it.
I could have cut & pasted _require_dm_linear(), but chose to go the route of a generic helper, _require_dm_target $FOO, because some day someone will need the zero target, the error target, or who knows.

Quoted 6 lines

Add the helper, use it in test generic/085, and convert _require_dm_flakey, _require_dm_snapshot, and _dmerror_required with this new helper.
