Keep in mind that CONFIG_CGROUP_MEM_RES_CTLR is not enabled by default because of this (enabling it, CONFIG_RESOURCE_COUNTERS, and CONFIG_CGROUPS increases the size of the kernel text by ~1%), and it's becoming increasingly important for certain workloads to be notified of low memory conditions without any restriction on its usage other than the amount of RAM that the system has so that they can trigger internal memory freeing, explicit memory compaction from the command line, drop caches, reducing scheduling priority, etc. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
