Subject: Incorrect accounting of irq into the running task

Hi  Venkatesh,

I  have  applied   the  following   patches   for  the  incorrect
accounting   of   irq  into  the  running  task .


[PATCH] x86: Add IRQ_TIME_ACCOUNTING
[e82b8e4ea4f3dffe6e7939f90e78da675fcc450e]
[PATCH] sched: Add IRQ_TIME_ACCOUNTING, finer accounting of irq time
[b52bfee445d315549d41eacf2fa7c156e7d153d5]

[PATCH] sched: Do not account irq time to current task
[305e6835e05513406fa12820e40e4a8ecb63743c]
[PATCH] sched: Export ns irqtimes through /proc/stat
[abb74cefa9c682fb38ba86c17ca3c86fed6cc464]



But   still  the      stime   and  utime    of   the   process  in
/proc/pid/stat     is    high  .    I  think   the  above  patches  does
not   update
The  stime  and  utime  values     in    /proc/pid/stat  .


Or  am  I  missing   anything  ?


Regards,
Shaiju.
