From: Hugh Dickins <hugh@veritas.com> Date: Tue, 12 Nov 2002 17:43:40 +0000 (GMT) Sorry, I still don't get it. If the flush_cache_page is doing something necessary, then won't a user access in between it and invalidating pte undo what was necessary? And if it's not necessary, why do we do it? (For better performance would be a very good reason.) If there are other writable mappings of the page, we can't swap it out legally. - 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/
