Subject: [PATCH 1/17] cramfs: use read_mapping_page
Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org

read_mapping_page_async() is going away, so convert its only user to
read_mapping_page().  This change has not been benchmarked, however, in
order to get real parallelism this wants something completely different,
like __do_page_cache_readahead(), which is not currently exported.
