ergo, there is no point in futzing with the pagecache_lock *at all* until either TUX is merged, or we decide to support large-scale NUMA hardware well Or your "1a", "other sendfile applications", right?
I really still feel (and will try to show with numbers) that the copy being present is not so important. Like I have stated on other occaisions, several platforms do not harm L2 cache state during copies, new lines are never brought in.
I expect x86 systems to move more in this direction if they aren't somewhat there already. - 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/
