Hi Kamezawa-san, I have a suggestion for css_id numbering. How about using the same numbering scheme as process ID for css_id instead of idr? It prevents the same ID from being reused quickly. blkio-cgroup can benefit from it. If some pages still have an old ID, it can somewhat prevents IOs associated with those pages from being charged for a new cgroup which are reusing the old ID. Please condier it. Thanks, Ryo Tsuruta _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
