Yes, it does mean that. Draining epoch callbacks is done by having the thread doing the drain bind itself to each cpu in turn, so it'll block if for any reason it can't be scheduled any runtime on some cpu (such as if a cpu is 100% busy at a priority that doesn't let it be preempted by the drain). -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "[email protected]"
