Hi, I had a quick look at recent 2.5 kernel Ben Lahaise's AIO code and I made some tests. These let me think that AIO pread/pwrite requests in 2.5 are handled synchronously using usual path (do_generic_file_read, etc). Even if I know there were many changes in this topic between 2.4 and 2.5, I find 2.5 AIO code very simple... I'd like to know which AIO support is already in 2.5. Is there only the AIO core (request submitting, getting events back, etc) but nothing for real asynchronous request processing support ? I know sockets AIO are not ready yet. Maybe kernel developers don't want to merge file AIO without sockets AIO ? Is the full AIO support planned to be merged before 2.6 ?
