Subject: [PATCH 2/2] mm: swap: Convert mark_page_lazyfree() to mark_folio_lazyfree()
Date:   Wed, 7 Dec 2022 10:34:31 +0800
Message-ID: <20221207023431.151008-2-wangkefeng.wang@huawei.com>

Precedence: bulk

mark_page_lazyfree() and the callers are converted to use folio,
this rename and make it to take in a folio argument instead of
calling page_folio().
