Followups: performance counters, ksplice, and fsnotify

I was a big fan of Ingo and Thomas, buying into the CFS, hrtimer, and dyntick hype but in retrospect (tbench regressions, general lack of quality in kernels 2.6.23+) they seem to have an easier than others time getting big/dangerous changes in.

I hope that Linus is more careful with crack projects from this duo in the future. CFS seemed to go in about 4 kernels too early judging by the shotgun patches applied since.
