I don't think it is. I think the RH announcement refers to their intent
to quickly stabilize some of the upcoming Linux 2.5 code and package it
separately for "enterprise" customers. If that's correct, the Linux 2.5
asynchronous I/O implementation will likely be Ben LaHaise's:

I agree with Greg -- it looks like it could definately improve Pg's
performance.
Cheers,
Neil
