From 794a4cb3d2f7c105112f9b59525533f00ac06006 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Tue, 1 Jan 2019 00:19:30 -0800 Subject: nvme: remove the .stop_ctrl callout It is used now just to flush error recovery and reconnect work items in the RDMA and TCP transports, which can simply be moved to the corresponding teardown routines.
