This is a valid fix but not the one that the commit message and
upstream commit hash refer to.  This diff matches:

commit 1786dbf3702e33ce3afd2d3dbe630bd04b1d2e58
Author: Dmitry V. Levin <ldv@altlinux.org>
Date:   Thu Feb 16 18:05:45 2017 +0300

    uapi: fix linux/rds.h userspace compilation error

which has almost the same subject line.

Maybe you should cherry-pick commit
feb0869d90e51ce8b6fd8a46588465b1b5a26d09 for real as well (in all
branches).
