Subject: [PATCH 02/10] mm: Remove PageSwapBacked
Date: Wed, 21 Aug 2024 20:34:35 +0100 [thread overview]
Message-ID: <20240821193445.2294269-3-willy@infradead.org> (raw)
In-Reply-To: <20240821193445.2294269-1-willy@infradead.org>
This flag is now only used on folios, so we can remove all the page
accessors.
