Today I committed the updated linux aio stuff to p4. It’s a module now, so it can be loaded as needed. I also updated the p4 diff in the wiki, so anyone can download and test it (please do it!).
Major features in the p4 diff are futexes and TLS for amd64. So if you own an amd64 system please download the patch and give it a try. I’m interested in reports for linux-firefox, skype, realplayer and acroread on amd64.
There’s one known bug with the mmap behavior on amd64 (even in current). I don’t know if this only affects the LTP tests or real world applications, but because there’s much time between the mmap commits and the report, I think it’s only a problem for the regression tests and not a problem which shows up in typical usage scenarios.
