From 8440cdc77577e5177153e121229cff73c0ba4e6c Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 7 Aug 2019 18:44:12 +0200 Subject: [PATCH] IB: directly cast the sockaddr union to aockaddr Like commit 641114d2af31 ("RDMA: Directly cast the sockaddr union to sockaddr") we need to quiet gcc 9 from warning about this crazy union. That commit did not fix all of the warnings in 4.19 and older kernels because the logic in roce_resolve_route_from_path() was rewritten between 4.19 and 5.2 when that change happened.
