Sorry, I might have missed this comment of yours. The
"cpuset.cpus.exclusive" file lists all the CPUs that can be granted to its
children as exclusive CPUs. The cgroup root is an implicit partition root
where all its CPUs can be granted to its children whether they are online or
offline. "cpuset.cpus.effective" OTOH ignores the offline CPUs as well as
exclusive CPUs that have been passed down to existing descendant partition
roots so it may differ from the implicit "cpuset.cpus.exclusive".
Howewer, there's no "cpuset.cpus" configurable nor visible on the root
cgroup. So possibly drop this hunk altogether for simplicity?
Ah, you are right. I thought there was a read-only copy in cgroup root.
Will correct that.
Thanks,
