Do you really want to do memory allocation in the exit path? That

I think we just need a counter there - let everyone count down as they
exit and the last one trigger the completion, no?
Yeah that's a good point, that'd be cleaner too. I'll change it and test
that.
Here's a cleaner variant that pairs the completion even with an atomic
count. Works for me as well.
I like this version. I ran it though the libaio test harness and
xfstests aio tests and it passed.
Thanks, Jens!
