Subject: [PATCH v3 09/13] mm/memory-failure: remove obsolete comment in unpoison_memory()
Date: Wed, 12 Jun 2024 15:18:31 +0800 [thread overview]
Message-ID: <20240612071835.157004-10-linmiaohe@huawei.com> (raw)
In-Reply-To: <20240612071835.157004-1-linmiaohe@huawei.com>
Since commit 130d4df57390 ("mm/sl[au]b: rearrange struct slab fields to
allow larger rcu_head"), folio->_mapcount is not overloaded with SLAB.
Update corresponding comment.
