Remove test_generic_01.sh since block layer may reorder I/O, making the test prone to false positives. Apply the improvements to test_generic_02.sh instead, which supposes for covering ublk dispatch io order. Rework test_generic_02 to verify that ublk dispatch doesn't reorder I/O by comparing request start order with completion order using bpftrace. The bpftrace script now: - Tracks each request's start sequence number in a map keyed by sector - On completion, verifies the request's start order matches expected completion order - Reports any out-of-order completions detected The test script: - Wait bpftrace BEGIN code block is run - Pins fio to CPU 0 for deterministic behavior - Uses block_io_start and block_rq_complete tracepoints - Checks bpftrace output for reordering errors Reported-and-tested-by: Alexander Atanasov <alex@zazolabs.com> Signed-off-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |
