[PATCH 1/2] lightnvm: create cmd before allocating request

From: Javier GonzÃlez
Date: Wed May 03 2017 - 05:19:39 EST


Create nvme command before allocating a request using
nvme_alloc_request, which uses the command direction. Up until now, the
command has been zeroized, so all commands have been allocated as a
read operation.
