Which is bogus. I had removed it in the version of the patch that I posted in early September, but apparently it crept back in. > Anyway, this leads to each tick being accounted twice if the > deterministic > accounting is not enabled -- first by timer_interrupt() and then by the > hrtimers core, doesn't it? Yep. Actually, I thought I was told that with CFS, the total process time was accounted accurately using sched_clock(), then apportioned between utime and stime (using counts of ticks in user/system state, which are somewhat inaccurate). At the time I thought that would be OK, but now I'm not so sure.
