selftests: ublk: derive TID automatically from script name

2026-01-31T13:36:41Z

Add automatic TID derivation in test_common.sh based on the script filename. The TID is extracted by stripping the "test_" prefix and ".sh" suffix from the script name (e.g., test_loop_01.sh -> loop_01). This removes the need for each test script to manually define TID, reducing boilerplate and preventing potential mismatches between the script name and TID. Scripts can still override TID after sourcing test_common.sh if needed. Reviewed-by: Caleb Sander Mateos Signed-off-by: Ming Lei Signed-off-by: Jens Axboe

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
