Also, in general, the comments seem to talk about capturing metadata at the time that a connection is opened, but the actual code seems to capture metadata all over the place. I think it needs to be very clear, both in the code and the interface, when metadata is captured. And the ns_eq stuff is too far buried (and not even contained in this patch!) to be easily verified as being correct, whatever correct means in that context. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
