Subject: [PATCH 00/13] ublk: one driver bug fix and selftest change
Date: Mon, 7 Apr 2025 21:15:11 +0800 [thread overview]
Message-ID: <20250407131526.1927073-1-ming.lei@redhat.com> (raw)
The 1st patch fixes kernel panic caused by aborting zc request, which
can be observed by the added stress_03/stress_04 tests.
The other patches are ublk selftest change:
- two bug fixes(2, 3)
- cleanup (4, 5)
- allow to run tests in parallel(6), also big simplification on
test script
- add two stress tests for zero copy(7)
- kublk misc change(8, 9, 10), helps for evaluating performance
- support target specific command line, so help to add new
target(Uday is working on fault-inject target) (11)
- add two tests for covering recovery features(12)
- add one heavy io & remove test over recovery enabled device(13),
which can catch io hang triggered by several recent patches.
Thanks,
Ming Lei (13):
