Subject: [PATCH 09/12] jbd2: Replace obvious uses of b_page with b_folio
Date: Thu, 15 Dec 2022 21:43:59 +0000 [thread overview]
Message-ID: <20221215214402.3522366-10-willy@infradead.org> (raw)
In-Reply-To: <20221215214402.3522366-1-willy@infradead.org>
These places just use b_page to get to the buffer's address_space
or have already been converted to folio.
