[cgroup/for-6.19 PATCH 0/3] cgroup/cpuset: Additional housekeeping check & cleanup

From: Waiman Long
Date: Sun Nov 02 2025 - 20:34:57 EST


The first two patches are based on the two cpuset patches from the
"timers: Exclude isolated cpus from timer migration" patch series [1]
with some minor modifications. They add additional nohz_full housekeeping
mask check to ensure that there is at least one common housekeeping
CPU that is not domain and nohz_full isolated.

The last patch is another cleanup patch to simplify the current
partition code.
