+From 3dda662bebb81666d009635df1055ba5c1e17b52 Mon Sep 17 00:00:00 2001
+From: Philip Withnall <pwithnall@endlessos.org>
+Date: Wed, 11 Nov 2020 18:16:17 +0000
+Subject: [PATCH 04/29] tests: Drop unnecessary volatile qualifiers from tests
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+These variables were already (correctly) accessed atomically. The
+`volatile` qualifier doesn’t help with that.
+
+Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
+
+Helps: #600
+Upstream-Status: Backport [https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719]
