SubjectRe: Re. Revised [PATCH 3/3] mm/readahead: Remove the check for ra->ra_pages
>  The check for ra->ra_pages is not required since fs like tmpfs which have
> ra_pages set to 0 don't use filemap_fault as part of their VMA ops (it uses
> shmem_fault). Also, page_cache_sync_readahead does its own check for ra_pages.
