Hi Tejun, this actually reminds me of something that's been on my todo list to report for some time, but I haven't had time to find the source of the bug... And maybe it's already been reported... but If I do cd /sys/fs/cgroup/memory mkdir b cd b echo 1 > memory.use_hierarchy echo 5000 > memory.limit_in_bytes cat memory.limit_in_bytes 8192 mkdir c cd c cat memory.use_hierarchy 1 cat memory.limit_in_bytes 9223372036854775807 echo $$ > tasks bash <killed> So it seems the hierarchy is being enforced, but not reported in child limit_in_bytes files.
