Dear all:
I know complete will wake up the process who call wait_complete.
Is there any methods I can use to measure how long from calling
complete to the process that detect done=1?
Regards,
miloody

returned value of wait_for_completion_timeout ?

No.
I want to measure the duration of complete to the time of wake up
process who is pending on wait.

Ah, Ok, Got it...
I would do a copy of jiffies before the complete and do a diff for
jiffies after the
wait_for_ ...

I suppose there would be much more better/optimized way ....

thank you.
