Subject: [PATCH 09/29] gio: Drop unnecessary volatile qualifiers from internal
 variables
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]
