I'll have to think about this some more.

Any further thoughts on this after a few days worth of pondering?

Sorry about the delay, with the merge window and me being sick for a
couple of days I didn't get around to this.

After thinking it over some more, I guess I'm ok with your approach.
The table-driven patch makes me a bit happier, and I guess not very

Are there other users outside of Solace? It would be good to get comments..

I know of quite a few storage/db products that use AIO. The most
recent high profile project that have been reporting issues with AIO
on XFS is http://www.scylladb.com/. That project is architected
around non-blocking AIO for scalability reasons...

Cheers,

Dave.
