From 7939f904600018aeed9d8cc9d19ca37c7e96f3d1 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Wed, 4 Oct 2017 10:03:52 -0400 Subject: Clean up "show api ring" debug CLI Add a primary svm_region_t pointer to the api_main_t so we can always find the primary region, even when processing an API message from a memfd segment.
