I mentioned that to Linus once and he said the entire idea was bogus. With the recent tcp_recvmsg() preemption issue thread, I agree with his sentiments even more than I did previously. What needs to happen is to liberate the locking so that input packet processing can occur in parallel with tcp_recvmsg(), instead of doing this bogus backlog thing which can wedge TCP ACK processing for an entire quantum if we take a kernel preemption while the process has the socket lock held. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
