Re: [PATCH v4 00/11] Dynamic Housekeeping Management (DHM) via CPUSets

[Jing Wu <realwujing@gmail.com>]

Hi all,

Gentle ping on this series - it has been quiet for a couple of months
since v4 went out, so checking whether it is stuck in a review queue
or just hasn't been picked up yet.

For context, v4 rebuilds the series around the CPU-by-CPU hotplug
cycling approach that Thomas suggested during v3 review, replacing the
RCU-swap-mask/callback mechanism from earlier versions. Patches 1-9
cover sched/isolation, tick/nohz, context_tracking, watchdog and the
cpuset driver logic; 10-11 are docs and selftests.

One thing worth flagging: v4 deliberately does not touch RCU/nocb
offload state. That piece is still being worked out in a separate,
ongoing discussion on Waiman's nohz_full/managed_irq series [1], where
the open question is how to change the nocb mask without paying a
stop_machine latency spike. We scoped it out of v4 so review of this
series would not need to wait on that RCU decision - happy to fold in
RCU/nocb support as a follow-up once that discussion converges.

Any review, even partial (a single patch or a design-level concern),
would be very helpful at this point.
