sched: show length of runqueue clock deactivation in /proc/sched_debugwip-fix3
The runqueue clock update should obviously not be skipped for
prolonged times (otherwise the consumed time is not correctly kept
track of). This patch measures the time between setting and clearing
the rq->skip_clock_update flag. The maximum observed value is exported
in /proc/sched_debug.
