+Subject: [PATCH 26/48] printk: Track nbcon consoles
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.8/older/patches-6.8.2-rt11.tar.xz
+
+Add a global flag @have_nbcon_console to identify if any nbcon
+consoles are registered. This will be used in follow-up commits
+to preserve legacy behavior when no nbcon consoles are registered.
