[PATCH] memcg: Add a new sysctl parameter for automatically setting memory.high (Waiman Long) https://lore.kernel.org/20240623204514.1032662-1-longman@redhat.com
While memcg v1 has only single file for memory limit setting, namely memory.limit_in_bytes, memcg v2 has two files, memory.max and memory.high for the purpose. Users migrating from memcg v1 to memcg v2 usually sets only memory.max, and hence get problems sometimes. This patch add a new knob, memory_high_autoset_ratio, which allows setting memory.high as a ratio of memory.
