Subject: [PATCH 0/2] mm/migrate: 5.15 fixes for automatic demotion
Date: Fri, 17 Sep 2021 15:35:04 -0700 [thread overview]
Message-ID: <20210917223504.C140445A@davehans-spike.ostc.intel.com> (raw)
This contains two fixes for the "automatic demotion" code which was
merged into 5.15:
* Fix memory hotplug performance regresssion by watching
suppressing any real action on irrelevant hotplug events.
* Ensure CPU hotplug handler is registered when memory hotplug
is disabled.
