cgroup/rstat: add cgroup_rstat_cpu_lock helpers and tracepoints (2024-05-14 09:43:17 -1000)
----------------------------------------------------------------
cgroup: Changes for v6.10
- The locking around cpuset hotplug processing has always been a bit of mess
which was worked around by making hotplug processing asynchronous. The
asynchronity isn't great and led to other issues. We tried to make the
behavior synchronous a while ago but that led to lockdep splats. Waiman
took another stab at cleaning up and making it synchronous. The patch has
been in -next for well over a month and there haven't been any complaints,
so fingers crossed.
- Tracepoints added to help understanding rstat lock contentions.
- A bunch of minor changes - doc updates, code cleanups and selftests.
