Don't think that would help any in this situation. The thing to look out for are RT tasks running with a different uid than 0. This patch would only stop a task from obtaining RT class scheduling when already in a (misconfigured) group. If the task is RT and then switches group another - similar - thing is needed. Does this artsmessage thing also run with RT priority? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
