From: Christoph Hellwig Date: Thu, 3 Dec 2015 16:52:05 +0000 (-0700) Subject: NVMe: fix build with CONFIG_NVM enabled X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac02dddec63385ffef1397d3f56cec4108bcafe9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git NVMe: fix build with CONFIG_NVM enabled 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 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.
