It is possible to have parallel attach operations to the same cpuset in progress. To avoid possible corruption of single set of DL BW data in the cpuset structure, we have to disallow parallel attach operations if DL tasks are present. Attach operations can still proceed in parallel as long as no DL tasks are involved. This patch also stores the CPU where DL BW is allocated and free that BW back to the same CPU in case cpuset_can_attach() is called. Signed-off-by: Waiman Long <longman@xxxxxxxxxx>
Juri, this patch is an addendum to your series to address the issues that I found from the cpuset point of view.
