Johannes Weiner 15e7b87676 nommu: ramfs: don't leak pages when adding to page cache fails ... When a ramfs nommu mapping is expanded, contiguous pages are allocated and added to the pagecache. The caller's reference is then passed on by moving whole pagevecs to the file lru list. If the page cache adding fails, make sure that the error path also moves the pagevec contents which might still contain up to PAGEVEC_SIZE successfully added pages, of which we would leak references otherwise.
