From b726ec972cf2122137fbc47847b4fcc7b3bc2801 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 6 May 2019 09:38:47 -0400 Subject: libceph: make ceph_pr_addr take an struct ceph_entity_addr pointer GCC9 is throwing a lot of warnings about unaligned accesses by callers of ceph_pr_addr. All of the current callers are passing a pointer to the sockaddr inside struct ceph_entity_addr. Fix it to take a pointer to a struct ceph_entity_addr instead, and then have the function make a copy of the sockaddr before printing it.
