ufs_get_locked_page(): make sure we have buffer_heads callers rely upon that, but find_lock_page() racing with attempt of page eviction by memory pressure might have left us with * try_to_free_buffers() successfully done * __remove_mapping() failed, leaving the page in our mapping * find_lock_page() returning an uptodate page with no buffer_heads attached.
