CIFS: FS-Cache: Uncache unread pages in cifs_readpages() before freeing them
In cifs_readpages(), we may decide we don't want to read a page after all - but the page may already have passed through fscache_read_or_alloc_pages() and thus have marks and reservations set. Thus we have to call fscache_readpages_cancel() or fscache_uncache_page() on the pages we're returning to clear the marks. NFS, AFS and 9P should be unaffected by this as they call read_cache_pages() which does the cleanup for you.
