Process accounting in interrupt diabled cases
...nk this may be a process accounting bug.
If interrupts are disabled for a considerable amount of time ( say
multiple ticks), the process accounting code will still account a single
tick for such cases, on the next interrupt tick.
Shouldn't we have some way to fix that case like we do for NO_HZ
restart_sched_tick case, where we account for multiple idle ticks.
IOW, doesn't process accounting need to account for these cases when
interrupts are disabled for more than one tick period?
I stumbled across this while trying to find a solution to figure out the
amount of stolen time from Linux, when it is ru...
