Sorry for the delay (I did write a reply, but probably forget to sent). musl and glibc support all of them, but uclibc-ng doesn't have SCHED_DEADLINE. (and SCHED_RESET_ON_FORK). I'll send v2 with SCHED_DEADLINE fallback. I guess SCHED_RESET_ON_FORK would deserve it's own test (man sched(7): when set, children created by fork(2) do not inherit privileged scheduling policies). Kind regards, Petr

Either write the test or at least create a github issue.

Either write the test or at least create a github issue. https://github.com/linux-test-project/ltp/issues/905 Marked as easyhack and wait some time to let new comers to take it before implementing it myself. Kind regards, Petr
