I'm curious where the out-of-fds "event groups" discussion happened, as I don't recall seeing it on linux-kernel.

I think the file descriptor limit was one of the complaints made about the perf_event interface when it was first introduced, it's nice they're finally getting around to looking into the issue, as it's fairly easy to run into the problem on a moderately sized system.
