Subject: delayacct regression in 2.6.24 git

Hi, Ingo,

I missed commit 75d4ef16a6aa84f708188bada182315f80aab6fa
"sched: fix delay accounting performance regression"

Without these changes, I find that delay accounting does
not work as expected, I see zeros in the field for virtual,delay
and count(s).

CPU             count     real total  virtual total    delay total
                    0      535861848              0              0


This breaks existing delay accounting behaviour.

Am I missing something?
