Hello Jeremy,

Yes! And 512b write IOps is improved! That's great!

This patch (look.txt on 20140408) is tested under my environment
whole yesterday afternoon,
and the 'strace' and 'perf top' shows no fcntl() related calls in the log.

The iometer 512b sequential write shows following result,
Before applying this patch: 75333 IOps
After applying this patch: 82691 IOps

About EAGAIN,
i would try to setup a high-latency network and test again,
Thanks for your time.

Jones
