Ben, I suppose you're talking about the following case: pagecache code has LRU page nonpagecache code does page_cache_get() pagecache code does page_cache_release() nonpagecache code does __free_pages_ok() on LRU page: BOOM. Is my thinking correct ? If so, I don't see why Ed's trace BUGs at rmqueue first: It should bug at __free_pages_ok() PageLRU check. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
