This could be done. I just wanted to post this RFC for now, just in case someone found an issue with this design. When I get back home, I'll complete this, and work with Frederic to get a RFC patch set with perf working.
I don't want to rush this out as it can get complex and I want us to "learn" the correct way of enabling this for perf. Although, it would be nice to get this into 2.6.40. Perhaps we should be conservative and aim for 2.6.41 and let it settle for a release.
