Having taskqueue_enqueue() which could silently (?) not enqueue the given task is huge and IMO risky change to the KPI. If doing it, I think that there should be a new function to enqueue, which is allowed to fail, unlike taskqueue_enqueue(). BTW, the man page for taskqueue(9) is wrong, taskqueue_enqueue(9) always succeed now and always returns 0 (ignoring the ushort overflow). _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
