Hello Jens,
This patchset cleans up ublk selftests and add more tests:
- two bug fixes(1, 2)
- cleanup (3, 4)
- allow to run tests in parallel(5), also big simplification on
test script
- add two stress tests for zero copy(6)
- kublk misc change(7, 8, 9), helps for evaluating performance
- support target specific command line, so help to add new
target(Uday is working on fault-inject target) (10)
- add two tests for covering recovery features(11)
- add one heavy io & remove test over recovery enabled device(12),
which can catch io hang triggered by several recent patches.
- the last patch is for making sure ublk temp file is cleaned up
if test is skipped
With this change, kernel built-in ublk selftests can :
- cover almost all tests done by ublksrv 'make test T=generic', which has
been effective to capture driver issue early, so it will make ublk driver
development more efficiently
- add more stress tests for covering ublk zc feature, which has found one
kernel panic issue introduced recently, fix merged already
- help to add new tests, such as per-target command line, which
will help to write fault-inject target
Thanks,
V2:
- use ARRAY_SIZE() (Johannes Thumshirn)
- drop one driver bug fix
- fix ublk temp file cleanup
- improve document
