From 81f03fedcce7ee7e83c37237ecaa2f68aad236fd Mon Sep 17 00:00:00 2001 From: Jon Derrick Date: Mon, 10 Aug 2015 15:20:41 -0600 Subject: NVMe: Add nvme subsystem reset IOCTL Controllers can perform optional subsystem resets as introduced in NVMe 1.1. This patch adds an IOCTL to trigger the subsystem reset by writing "NVMe" to the NSSR register.
