From 2461a8dd38bea3cb5b1c1f0323794483292fb03f Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Sun, 24 Jul 2016 09:29:51 +0300 Subject: nvme-rdma: Remove duplicate call to nvme_remove_namespaces nvme_uninit_ctrl already does that for us. Note that we reordered nvme_rdma_shutdown_ctrl and nvme_uninit_ctrl, this is perfectly fine because we actually want ctrl uninit (aen, scan cancellation and namespaces removal) to happen before we shutdown the rdma resources. Also, centralize the deletion work and the dead controller removal work code duplication into __nvme_rdma_shutdown_ctrl that accepts a shutdown boolean.
