Subject: [PATCH 0/2] cgroup/cpuset: Miscellaneous cleanup
Date: Sun, 19 Oct 2025 22:32:05 -0400 [thread overview]
Message-ID: <20251020023207.177809-1-longman@redhat.com> (raw)
This series consists of 2 independent cleanup patches. The first one
eliminates the tracking of the number of child partitions as that value
isn't that useful anymore simplifying the code. The second one change
callback_lock into raw_spinlock_t to reduce cpuset operation overhead in
a PREEMPT_RT setting.
Waiman Long (2):
cgroup/cpuset: Don't track # of local child partitions
cgroup/cpuset: Change callback_lock to raw_spinlock_t
