Better response to interrupts is good, but it comes at the cost of longer latency acquiring the lock (in the case where an interrupt happens while we are waiting for the lock, and the lock is freed while we are off executing the interrupt handler). Any suggestions on how to measure the trade-off here? Possibly it doesn't matter because this may only be significant when the lock is heavily contended and you are probably aleady hosed in this case. -Tony -- 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/
