From 6db28eda266052f86a6b402422de61eeb7d2e351 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Fri, 10 Feb 2017 18:15:49 -0500 Subject: [PATCH] nvme/pci: Disable on removal when disconnected If the device is not present, the driver should disable the queues immediately. Prior to this, the driver was relying on the watchdog timer to kill the queues if requests were outstanding to the device, and that just delays removal up to one second.
