Subject: [PATCH 1/4] mm: pagevec: add folio_batch_reinit()
Date: Thu, 22 Dec 2022 19:48:30 +0000 [thread overview]
Message-ID: <f05b330bc806aa64f6ae5d0001ea9d29d47da354.1671738120.git.lstoakes@gmail.com> (raw)
In-Reply-To: <cover.1671738120.git.lstoakes@gmail.com>
This performs the same task as pagevec_reinit(), only modifying a folio
batch rather than a pagevec.
