Nope, that was what you /thought/ it was.
My debugging code has shown it to be something else, lru_cache_add() is called for pages which are already on the LRU list...
I know this because: 1) the boobytraps in rmqueue() and page_reclaim() never trigger 2) the ->next->prev pointer is /consistent/ (this wouldn't be the case after a list_del and being hauled through rmqueue, etc...)
