selftests: ublk: add _ublk_del_dev helper function

2026-01-31T21:56:28Z

Add _ublk_del_dev() to delete a specific ublk device by ID and use it in all test scripts instead of calling UBLK_PROG directly. Also remove unused _remove_ublk_devices() function. Signed-off-by: Ming Lei Signed-off-by: Jens Axboe

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 stop command with --safe option

2026-01-12T22:07:31Z

Add 'stop' subcommand to kublk utility that uses the new UBLK_CMD_TRY_STOP_DEV command when --safe option is specified. This allows stopping a device only if it has no active openers, returning -EBUSY otherwise. Also add test_generic_16.sh to test the new functionality. Signed-off-by: Ming Lei Signed-off-by: Jens Axboe
