Btw, aio_sendfile and aio_sendfile_path use naive and actually the simplest approach of async IO - it just stupidly blocks on sending or resends (like repeated sending approach) - I'm a bit lazy to use kevent there, since there is _no_ gain after a bit more deep analysis (hint: there are multiple IO threads, some of them might block), and network AIO does not exist (yet, kevent status is in hinged state, and I was asked to postpone additional feature addons, which otherwise could happen a bit more frequently then current kevent/kernel releases), due to kevent future is indeterminate... -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
