I haven't seen any kernel issues with it, and I've had it in my kernel for a long time. There aren't very many end-user programs that make calls to sched_setscheduler(), but xmms does. One of my own programs does too, and I've had no problems. OF course, leaving it out is generally harmless too, since sched_setscheduler() is a no-op (well, a log message) when your kernel doesn't have POSIX_PRIORITY_SCHEDULING. Assuming xmms still runs O.K. without it, of course. Daniel ~~~~~~ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
