cpuset.cpus and cpuset.mems are the configured masks, and we need to export effective masks to userspace, so users know the real cpus_allowed and mems_allowed that apply to the tasks in a cpuset. v2: - export those masks unconditionally, suggested by Tejun. Signed-off-by: Li Zefan <redacted>
I applied this patch but there's a pending patchset to split legacy and dfl cftype arrays, so maybe doing it separately makes more sense now, I'm not sure. Anyways, we need to review cpuset interface for the default hierarchy anyway. At least the memory pressure knobs should go. It's measuring something which is completely implementation dependent. Thanks. -- tejun
