[Qemu-block] [PATCH v2 0/5] iotests: Selfish patches

[Max Reitz]

Hi,

These are some rather selfish iotests patches.  The first patch helps me
personally because I tend to run the tests over SSH and forget to set
$DISPLAY.  That makes test 139 skip the tests annotated with
skip_if_unsupprted(), because iotests.py can no longer determine the
list of whitelisted formats.

Patches 2 through 5 are specifically for RHEL.  We have not whitelisted
null-aio, so it would be nice if tests didn’t require it.  Sorry, I
don’t have a better reason to give.
In all seriousness, null-co is used widely in many tests, it basically
is our standard null driver.  Tests should prefer it over null-aio, just
for consistency alone.  It is not completely unreasonable to treat
null-aio as optional.  I guess.


v2:
- Allow tests to use the unittest module’s skipTest() so it is possible
  to skip a test case in the setUp() method (new patch 3).  Then use
  this in patches 4 and 5 to skip all null-aio cases instead of falling
  back to null-co and thus running tests twice.

- Patch 1 needed to be rebased on
  4a715461c8eab628e79b1e6889d650455e043b88
  (“tests/qemu-iotests/check: Pick a default machine if necessary”)


git backport-diff against v1:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
