selftests: ublk: improve test usability

2025-03-10T22:24:42Z

Add UBLK_TEST_QUIET, so we can print test result(PASS/SKIP/FAIL) only. Also always run from test script's current directory, then the same test script can be started from other work directory. This way helps a lot to reuse this test source code and scripts for other projects(liburing, blktests, ...)

selftests: ublk: move zero copy feature check into _add_ublk_dev()

2025-03-10T22:24:42Z

Move zero copy feature check into _add_ublk_dev() since we will have more tests which requires to cover zero copy. Then one check function of _check_add_dev() has to be added for dealing with cleanup since '_add_ublk_dev()' is run in sub-shell, and we can't exit from it to terminal shell. Meantime always return error code from _add_ublk_dev(). Signed-off-by: Ming Lei Link: https://lore.kernel.org/r/20250303124324.3563605-8-ming.lei@redhat.com Signed-off-by: Jens Axboe
