Subject: [PATCH] nvme-pci: unquiesce dead controller queues
Git-commit: 1d39e6928cbd0eb737c51545210b5186d5551ba1
Patch-mainline: v4.18-rc1
References: bsc#1104967,FATE#325924
This patch ensures the nvme namsepace request queues are not quiesced
on a surprise removal. It's possible the queues were previously killed
in a failed reset, so the queues need to be unquiesced to ensure all
requests are flushed to completion.
