Dear Anthony, Dear Fajar, On may unit letters like 'G' while setting the values of the memory cgroup controller.
But note that memsw stands for the sum of memory and swap. Therefore, can't set memory.memsw.limit_in_bytes to a value *lower* than the actual value of memory.limit_in_bytes. In the other hand, you can't set memory.limit_in_bytes to a value *greater* than the actual value of memory.memsw.limit_in_bytes. Because the default is "unlimited", you first have to lower the value for memory before you be able to lower the memsw value. To my opinion this is no good interface design, but unfortunately that's the current state. Maybe we should send a patch upstream, to automatically rise memsw if mem should be set to a value greater than memsw and by the other hand lower mem, if memsw should be set below mem.
