selftests: ublk: organize test directories by test ID

2026-02-05T03:46:44Z

Set UBLK_TEST_DIR to ${TMPDIR:-./ublktest-dir}/${TID}.XXXXXX to create per-test subdirectories organized by test ID. This makes it easier to identify and debug specific test runs. Signed-off-by: Ming Lei Signed-off-by: Jens Axboe

selftests: ublk: increase timeouts for parallel test execution

2026-01-31T21:56:28Z

When running tests in parallel with high JOBS count (e.g., JOBS=64), the existing timeouts can be insufficient due to system load: - Increase state wait loops from 20/50 to 100 iterations in _recover_ublk_dev(), __ublk_quiesce_dev(), and __ublk_kill_daemon() to handle slower state transitions under heavy load - Add --timeout=20 to udevadm settle calls to prevent indefinite hangs when udev event queue is overwhelmed by rapid device creation/deletion Signed-off-by: Ming Lei Signed-off-by: Jens Axboe

selftests: ublk: add _ublk_sleep helper for parallel execution

2026-01-31T21:56:28Z

Add _ublk_sleep() helper function that uses different sleep times depending on whether tests run in parallel or sequential mode. Usage: _ublk_sleep Export JOBS variable from Makefile so test scripts can detect parallel execution, and use _ublk_sleep in test_part_02.sh to handle the partition scan delay (1s normal, 5s parallel).

selftests: ublk: track created devices for per-test cleanup

2026-01-31T21:56:28Z

Track device IDs in UBLK_DEVS array when created. Update _cleanup_test() to only delete devices created by this test instead of using 'del -a' which removes all devices. This prepares for running tests concurrently where each test should only clean up its own devices. Signed-off-by: Ming Lei Signed-off-by: Jens Axboe

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: simplify UBLK_TEST_DIR handling

2026-01-31T21:56:28Z

Remove intermediate TDIR variable and set UBLK_TEST_DIR directly in _prep_test(). Remove default initialization since the directory is created dynamically when tests run. Signed-off-by: Ming Lei Signed-off-by: Jens Axboe

selftests: ublk: move test temp files into a sub directory

2026-01-31T13:36:41Z

Create and use a temporary directory for the files created during test runs. If TMPDIR environment variable is set use it as a base for the temporary directory path. TMPDIR=/mnt/scratch make run_tests and TMPDIR=/mnt/scratch ./test_generic_01.sh will place test directory under /mnt/scratch Signed-off-by: Alexander Atanasov Signed-off-by: Jens Axboe

selftests: ublk: mark each test start and end time in dmesg

2026-01-31T13:36:41Z

Log test start and end time in dmesg, so generated log messages during the test run can be linked to specific test from the test suite. (switch to `date +%F %T`) Signed-off-by: Alexander Atanasov 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 integrity params test

2026-01-12T16:16:38Z

Add test case null_04 to exercise all the different integrity params. It creates 4 different ublk devices with different combinations of integrity arguments and verifies their integrity limits via sysfs and the metadata_size utility.
