In the end the revalidate only really matters when either the host queries the information. So I'm tempted to just apply patch 1 for now and skip the rest. _______________________________________________ linux-nvme mailing list linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
