From dd3c13f364e03e843d838bf925a5fc85513343ed Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Mon, 7 Jan 2019 17:48:28 +0100
Subject: [PATCH] tree-wide: always declare bitflag enums the same way
let's always use the 1 << x syntax. No change of behaviour or even of
the compiled binary.
(cherry picked from commit be0b7a1a66fd269b644124c4633088ab2224d1fb)
Resolves: RHEL-2857
