From 6fb271f1bc4ebc59bac0ff835c2e5197eac4b075 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Thu, 21 Jul 2022 08:33:58 +0800 Subject: [PATCH] nvme-fc: restart admin queue if the caller needs to restart queue Without restarting admin queue in __nvme_fc_abort_outstanding_ios(), it leaves controller not capable of handling admin pt request, and causes io hang. Fixes it by restarting admin queue if the caller of __nvme_fc_abort_outstanding_ios requires to restart queue.
