Subject: [PATCH v4 1/8] cgroup/cpuset: use hotplug_memory_notifier() directly
Date: Fri, 23 Sep 2022 11:33:40 +0800 [thread overview]
Message-ID: <20220923033347.3935160-2-liushixin2@huawei.com> (raw)
In-Reply-To: <20220923033347.3935160-1-liushixin2@huawei.com>
Since patch 316346243be6 has already updated the minimum gcc version to 5.1.
The previous problem mentioned in patch f02c69680088 is not existed. So we
can now revert to use hotplug_memory_notifier() directly rather than
register_hotmemory_notifier().
