Subject: [PATCH 033/135] NVMe: fix build with CONFIG_NVM enabled
[ Upstream commit ac02dddec63385ffef1397d3f56cec4108bcafe9 ]
Looks like I didn't test with CONFIG_NVM enabled, and neither did
the build bot.
Most of this is really weird crazy shit in the lighnvm support, though.
Struct nvme_ns is a structure for the NVM I/O command set, and it has
no business poking into it. Second this commit:
commit 47b3115ae7b799be8b77b0f024215ad4f68d6460
Author: Wenwei Tao <ww.tao0320@gmail.com>
Date: Fri Nov 20 13:47:55 2015 +0100
nvme: lightnvm: use admin queues for admin cmds
Does even more crazy stuff. If a function gets a request_queue parameter
passed it'd better use that and not look for another one.

Nope, this broke the build :(
Sasha, what happened? Why is this working for you?
I'm dropping this now...
