See vfs.git#work.aio; the crucial bits are in these commits:
keep io_event in aio_kiocb
get rid of aio_complete() res/res2 arguments
move aio_complete() to final iocb_put(), try to fix aio_poll() logics
The first two are preparations, the last is where the fixes (hopefully)
happen.
OK, refactored, cleaned up and force-pushed. Current state:
Al Viro (7):
keep io_event in aio_kiocb
aio: store event at final iocb_put()
Fix aio_poll() races
make aio_read()/aio_write() return int
move dropping ->ki_eventfd into iocb_destroy()
deal with get_reqs_available() in aio_get_req() itself
aio: move sanity checks and request allocation to io_submit_one()
Linus Torvalds (1):
pin iocb through aio.
