I already gave you my opinion on such code. There is no need for it. If your servers are loaded, in the same way you bump NFILES (and likely even other default configs), you bump up max_user_instances: $ echo NN > /proc/sys/fs/epoll/max_user_instances It requires no extra crud in the kernel, and it works pretty darn good. - Davide -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
