BugLink: http://bugs.launchpad.net/bugs/1442186

== Problem Description ==
NVMe device driver running with a Samsung SM1715 card fails (hits EEH)
w/nvme-user and htx tools

== Steps to Reproduce ==
 1. Install the nvme-user tools package and run the nvme_rw tool

or

 2. Install the htx I/O exerciser tool and run htx

== Fix ==
The patch is curently in an upstream subsystem maintainer's tree and
should land in the next upstream merge window:

http://git.kernel.org/cgit/linux/kernel/git/axboe/linux-block.git/commit/?h=for-next&id=f137e0f15101c0a0ff8a5d956042e50247f1fef9

== Testing ==
IBM has tested this patch on a v3.19 based Vivid kernel.  They confirm
the patch works as expected.  HTX is running over an hour w/o any
mis-compare.  It typically fails right away w/o this fix.
