Thanks a lot for fixing -1 in v3. I was thinking to merge v2 and fix -1 manually, but I'm really not sure if the test is meaningless for realtime. Was the test really written for CFS? It would be nice to get ack from any realtime developer. BTW test is working well on x86_64 SLES realtime kernel on VM, i.e. both you want to skip (RT) or warn about unreliable results (VM). That of course does not mean it's relevant for RT kernel. Kind regards, Petr -- Mailing list info: https://lists.linux.it/listinfo/ltp
