Hi Willy,
Here's a set of patches to expand the use of the readahead_control struct, essentially from do_sync_mmap_readahead() down. Note that I've been passing the number of pages to read in rac->_nr_pages, and then saving it and changing it certain points, e.g. page_cache_readahead_unbounded().
Also pass file_ra_state into force_page_cache_readahead().
Also there's an apparent minor bug in khugepaged.c that I've included a patch for: page_cache_sync_readahead() looks to be given the wrong size in collapse_file().
David --- David Howells (7): Fix khugepaged's request size in collapse_file() mm: Make ondemand_readahead() take a readahead_control struct mm: Push readahead_control down into force_page_cache_readahead() mm: Pass readahead_control into page_cache_{sync,async}_readahead() mm: Make __do_page_cache_readahead() use rac->_nr_pages mm: Fold ra_submit() into do_sync_mmap_readahead() mm: Pass a file_ra_state struct into force_page_cache_readahead()
