Subject: [PATCH v2 5/8] mm/memory-failure.c: remove PageSlab check in hwpoison_filter_dev
Date: Wed, 16 Feb 2022 17:14:28 +0800 [thread overview]
Message-ID: <20220216091431.39406-6-linmiaohe@huawei.com> (raw)
In-Reply-To: <20220216091431.39406-1-linmiaohe@huawei.com>
Since commit 03e5ac2fc3bf ("mm: fix crash when using XFS on loopback"),
page_mapping() can handle the Slab pages. So remove this unnecessary
PageSlab check and obsolete comment.
