OK, it's in -next now; there are several cleanups I'd put
into vfs.git#work.aio:
aio: all callers of aio_{read,write,fsync,poll} treat 0 and -EIOCBQUEUED the same way
aio_read_events_ring(): make a bit more readable
aio: shift copyin of iocb into io_submit_one()
aio: fold do_io_submit() into callers
Those are *not* on -next yet and if anybody has objections against
any of those, please yell. Individual patches in followups...
