Dear Maintainer,
Some processes in my system need to be limited when it comes to memory
consumption. I wanted to use cgroup v1 along with tools from the cgroup-tools
package to achieve the goal. Everything works well, but the limits can be
applied to RAM only. My machine has also a SWAP partition, and in such case,
when the limit is reached, kernel starts to use SWAP, and it does that without
any control. For instance, if I've set a limit of 1GiB of memory for firefox,
after reaching this limit, all the data would go to SWAP and fill it up slowing
also the system down. There's an option that could prevent this from happening:
CONFIG_MEMCG_SWAP_ENABLED , but it's not set and all the memory.memsw.* files
under /sys/fs/cgroup/memory/ don't exist. Could you set this option?
