You're right. I even signed off on your change.
Andrew,
Drop my "cpuset rmdir scheduling while atomic fix" patch.
Dinakar's dynamic-sched-domains-cpuset-changes.patch fixed it.
Dinakar's change wasn't quite the same as mine. It is actually the
better of the two - it reduces the dentry spinlock region, instead of
moving the cpuset_sem region outside the spinlock. I just ran my stress
test that shows this bug. Dinakar's fix is fine, as expected.
