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: add test to verify that feat_map is complete

2025-09-19T17:06:15Z

Add a test that verifies that the currently running kernel does not report support for any features that are unrecognized by kublk. This should catch cases where features are added without updating kublk's feat_map accordingly, which has happened multiple times in the past (see [1], [2]). Note that this new test may fail if the test suite is older than the kernel, and the newer kernel contains a newly introduced feature. I believe this is not a use case we currently care about - we only care about newer test suites passing on older kernels.
