From 3b24774e1fb90a40836e96e39a851a774679efff Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Wed, 27 Apr 2016 15:51:18 -0600 Subject: [PATCH] NVMe: Fix check_flush_dependency warning If the controller fails and is degraded after a reset, we need to kill off all requests queues before removing the inaccessble namespaces. This will prevent del_gendisk from syncing dirty data, which we can't due from a WQ_MEM_RECLAIM work queue.
