Subject: [PATCH 8/9] mm/z3fold: remove unneeded PAGE_HEADLESS check in free_handle()
Date: Sat, 19 Feb 2022 17:25:32 +0800 [thread overview]
Message-ID: <20220219092533.12596-9-linmiaohe@huawei.com> (raw)
In-Reply-To: <20220219092533.12596-1-linmiaohe@huawei.com>
The only caller z3fold_free() never calls free_handle() in PAGE_HEADLESS
case. Remove this unneeded check.
