Date: Fri, 11 Apr 2008 13:21:28 -0400 From: "Dan Upton" <upton.dan.linux@...il.com> To: linux-kernel@...r.kernel.org Subject: CFS rq lock question I'm poking around with some scheduler stuff, and there's something I'm not clear on for the CFS runqueue locks. The comments before __load_balance_iterator(...) in sched_fair.c suggests things can be dequeued even though the runqueue lock is held. Can things also be added to the queue while the lock is held? (Also, either way, what's the rationale that dequeueing is a safe procedure when somebody else holds a lock?) -dan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
