It'll be out of standard as timerfd is, w/out code savings. Look at the code and tell me what could be saved. Prolly the ten lines of the timer callback. Lines that you'll have to drop inside the current posix timer layer. Better leave standards alone, especially like in this case, when the savings are not there. - Davide - 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/
