From 079e3bc588465f6216bfc5ad61540b5db4616598 Mon Sep 17 00:00:00 2001 From: Logan Gunthorpe Date: Thu, 15 Jun 2017 14:12:23 -0600 Subject: switchtec: Add "running" status flag to fw partition info ioctl This flag lets userspace know which firmware partitions are currently in use as opposed to just active. "Active" means they will be in use for the next reboot, whereas "running" means they are currently in use. If an old kernel is in use, or the firmware doesn't support these fields, the new flag will not be set in the output.
