Subject: [PATCH v3 0/5] check: add option to rerun failed tests
Date:   Wed,  6 Jul 2022 13:23:07 +0200

This patchset adds support to loop on failed tests, as proposed by
Ted Ts'o in https://lwn.net/Articles/897061/:
  add a mode that will immediately rerun a failed test 25 or 100 times
  to establish a failure percentage.

Changes since previous version (v2), following Darrick's review:
- dropped RFC flag
- rebased atop v2022.07.03
- simplified test iterator
  + results stashed at the end of each iteration, rather than start of
    next / loop-exit
- dropped aggregate loop stats message from xunit report
- squashed full/dmesg/out.bad file retention patch with rerun patch

Changes since previous version (v1):
- rebased atop upstream v2022.06.26
- added a few extra cleanup commits
- append details for every rerun to xunit output
  + provide aggregate stats via <testcase status=X>
- extend _stash_test_status to call report hook, as well as save failure
  artifacts with a .rerun# suffix
