Subject: [PATCH v2 11/12] udf: Convert udf_adinicb_writepage() to memcpy_to_page()
Date: Wed, 25 Jan 2023 10:41:53 +0100 [thread overview]
Message-ID: <20230125094159.10877-11-jack@suse.cz> (raw)
In-Reply-To: <20230125093914.24627-1-jack@suse.cz>
Instead of mapping the page manually with kmap() atomic, use helper
memcpy_to_page(). Also delete the pointless SetPageUptodate() call.
