Hi Willy, Here's a set of patches to expand the use of the readahead_control struct, essentially from do_sync_mmap_readahead() down. It's on top of: http://git.infradead.org/users/willy/pagecache.git Also pass file_ra_state into force_page_cache_readahead(). The bugfix for khugepaged.c is included as that code is further changed here.
