Zorro,

As discussed on v1, this series fixes cleanup routines of
freeze tests without adding auto-cleanup in check.

I also took a closer look at some test cleanups and handled the
kill of background processes after unfreeze.

I tested that all the tests in the 'freeze' group that I modified
run to completion with no regressions.

I did not try to interrupt all the rest of the tests, because
interrupting a test at exact time that it is frozen is quite hard.

I did test that interrupting xfs/517 several times did not leave the fs
frozen.  Before the changes, it was rather easy to get it to leave a
frozen fs behind, because the freeze_loop() keeps the fs frozen around
half of the time that the test is running.

Thanks,
Amir.

Changes since v1:
- Remove auto-cleanup in check
- Add more kill+wait in cleanups where needed
- Change the cleanup routines of the freeze_loops

Amir Goldstein (3):
  fstests: add missing _require_freeze() to tests
  fstests: unfreeze fs on cleanup routines
  xfs/{422,517}: kill background jobs on test termination
