Subject: [PATCH 1/8] mm/memory-failure.c: minor clean up for memory_failure_dev_pagemap
Date: Thu, 10 Feb 2022 22:17:26 +0800	[thread overview]
Message-ID: <20220210141733.1908-2-linmiaohe@huawei.com> (raw)
In-Reply-To: <20220210141733.1908-1-linmiaohe@huawei.com>

The flags always has MF_ACTION_REQUIRED and MF_MUST_KILL set. So we do
not need to check these flags again.
