From 92911a55d42084cd285250c275d9f238783638c2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 26 Apr 2016 13:51:58 +0200 Subject: [PATCH] nvme: tighten up state check for namespace scanning We only should be scanning namespaces if the controller is live. Currently we call the function just before setting it live, so fix the code up to move the call to nvme_queue_scan to just below the state change.
