Subject: [PATCH v2 22/28] iomap,xfs: Convert ->discard_page to ->discard_folio
Date: Mon, 8 Nov 2021 04:05:45 +0000 [thread overview]
Message-ID: <20211108040551.1942823-23-willy@infradead.org> (raw)
In-Reply-To: <20211108040551.1942823-1-willy@infradead.org>
XFS has the only implementation of ->discard_page today, so convert it
to use folios in the same patch as converting the API.
