Subject: [PATCH 3/6] ps3disk: replace flush_kernel_dcache_page with flush_dcache_page
Date: Mon, 12 Jul 2021 08:09:25 +0200 [thread overview]
Message-ID: <20210712060928.4161649-4-hch@lst.de> (raw)
In-Reply-To: <20210712060928.4161649-1-hch@lst.de>
Pages passed to block drivers can be mapped page cache pages, so we
must use flush_dcache_page here instead of the more limited
flush_kernel_dcache_page that is intended for highmem pages only.
