+From 3c648457c284b4ba313b8591008d2e18ae4335eb Mon Sep 17 00:00:00 2001

+Subject: [PATCH 13/29] gatomic: Drop unnecessary volatile qualifiers from
+ internal variables
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It’s not necessary and provides no thread safety guarantees.
+
+The `volatile` qualifiers on the function arguments have to be kept, as
+they are (unfortunately) part of the API.
+
+Signed-off-by: Philip Withnall <pwithnall@endlessos.org>

+Helps: #600
+Upstream-Status: Backport [https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719]
