Subject: [PATCH 5/9] mm/mm_init.c: use hotplug_memory_notifier() directly
Date: Mon, 19 Sep 2022 16:31:48 +0800 [thread overview]
Message-ID: <20220919083152.1824305-6-liushixin2@huawei.com> (raw)
In-Reply-To: <20220919083152.1824305-1-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().
