From 58b99bd7f680c17dcea2cce2edcfd7fff0b99a01 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Thu, 11 Feb 2016 13:05:43 -0700 Subject: [PATCH] NVMe: Poll device while still active during remove A device failure or link down wouldn't have been detected during namespace removal. This patch keeps the device in the list for polling so that the thread may see such failure and initiate a reset. The device is removed from the list after disable, so we can safely flush the reset work as it can't be requeued when disable completes.
