From d3c3c0a841d5dafc5395be363996d619255a732f Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 17 Jun 2019 06:57:25 -0400 Subject: [PATCH] libceph: use TYPE_LEGACY for entity addrs instead of TYPE_NONE Going forward, we'll have different address types so let's use the addr2 TYPE_LEGACY for internal tracking rather than TYPE_NONE. Also, make ceph_pr_addr print the address type value as well.
