Hi Damien, Since these commits: scsi: block: Introduce ioprio hints scsi: block: ioprio: Clean up interface definition go into linux-next tree, ioprio_set can take the value of 8 as the PROCESS CLASS_BE ioprio parameter, returning success but actually it is setting to 0 due to the mask roundup. The LTP test case ioprio_set03[1] covers this boundary value testing, which starts to fail since then. This does not look as expected. Could you help to take a look? Thanks, Murphy [1] https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/syscalls/ioprio/ioprio_set03.c
