Yeah. Thanks so much. This is a new Smatch warning I'm working on.
It triggers a warning whenever __might_sleep() or __might_sleep() are
called and the prempt count is non-zero. I didn't know what the
"preempt_offset" argument was for.
I'll modify the check to only warn when "preempt_offset" is zero.
regards,
dan carpenter
