From 45862ebcc4883b1b6bc0701cd15cb2b68b140c5d Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Sun, 24 Jul 2016 09:26:16 +0300 Subject: [PATCH] nvme-rdma: Make sure to shutdown the controller if we can Relying on ctrl state in nvme_rdma_shutdown_ctrl is wrong because it will never be NVME_CTRL_LIVE (delete_ctrl or reset_ctrl invoked it). Instead, check that the admin queue is connected. Note that it is safe because we can never see a copmeting thread trying to destroy the admin queue (reset or delete controller).
