    ufs_get_locked_page(): make sure we have buffer_heads · 267309f3

    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.
