From 6bbf1acddeed0bfb345a5578f9fcada16f1e514f Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 20 May 2011 13:03:42 -0400 Subject: NVMe: Rework ioctls Remove the special-purpose IDENTIFY, GET_RANGE_TYPE, DOWNLOAD_FIRMWARE and ACTIVATE_FIRMWARE commands. Replace them with a generic ADMIN_CMD ioctl that can submit any admin command. Add a new ID ioctl that returns the namespace ID of the queried device. It corresponds to the SCSI Idlun ioctl.
