v2 seems ok to me.. all my comments were addressed, and I posted one more comment anyway, I dont touch annotate code that much to ack annotate core patches.. acking only portion of the patchset thanks, jirka -- 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/
