systemd offers MemoryLow for an individual units. It actually sets memory.low cgroup attribute, so this is OK. The problem is according to kernel dcouemtation, memory.low is limited by value set in parent cgroup and all parent cgroups have memory.low=0:
/sys/fs/cgroup/user.slice/user-1001.slice/user@1001.service/gnome-shell-wayland.service/memory.low:536870912 /sys/fs/cgroup/user.slice/user-1001.slice/user@1001.service/memory.low:0 /sys/fs/cgroup/user.slice/user-1001.slice/memory.low:0 /sys/fs/cgroup/user.slice/memory.low:0 which implies setting on lead cgroup has no effect. Is it necessary to explicitly set it on every ancestor? There is no clarification in systemd documentation and value is applied without any warning. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
