http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.7-rc3/2.6.7-rc3-mm2/broken-out/epoll-uses-rbtrees.patch Your patch is a revert of this change, it probably wont be accepted. epoll_ctl() is scalable, since it's O(log2(N)) : With 1 millions files descriptors, that means less than 20 nodes to lookup in the tree. In what situation do you think epoll_ctl() performance is bad ? -- 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/
