mm/readahead: Switch to page_cache_ra_order
do_page_cache_ra() was being exposed for the benefit of do_sync_mmap_readahead(). Switch it over to page_cache_ra_order() partly because it's a better interface but mostly for the benefit of the next patch. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
