Subject: [PATCH v3 3/6] mm/vmscan: activate swap-backed executable folios after first usage
Date: Mon, 25 Apr 2022 19:12:29 +0800 [thread overview]
Message-ID: <20220425111232.23182-4-linmiaohe@huawei.com> (raw)
In-Reply-To: <20220425111232.23182-1-linmiaohe@huawei.com>
We should activate swap-backed executable folios (e.g. tmpfs) after first
usage so that executable code gets yet better chance to stay in memory.
