Here is a patch to libaio which adds a timeout parameter to
io_queue_run() and removes io_queue_wait(). This makes my
earlier kernel patch to fs/aio.c unnecessary, since I removed
io_queue_wait() which was calling the io_getevents() syscall
with a zero number of events. This keeps the callback interface
in the library and allows a user process to wait for i/o's to
complete if it wants to. I also changed io_queue_run() to
batch up to 8 completions at a time, so it is more efficient.
This requires no kernel changes. I also updated the io_queue_run()
man page and that is in a separate patch.
Thoughts?
