From 39a9dd81f864aa20be896bb34b4bbc2501a2453d Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Tue, 14 May 2019 14:10:41 -0600 Subject: nvme-pci: Don't disable on timeout in reset state The reset state doesn't dispatch commands that it needs to wait for anymore. If a timeout occurs in this state, the reset work is already disabling the controller, so just reset the request's timer.
