From c222f80be55f6c17851af1c68a70ae4046c848e2 Mon Sep 17 00:00:00 2001 From: Sven Peter Date: Sat, 29 Aug 2026 10:08:37 +0200 Subject: [PATCH] thunderbolt: Mark discovered tunnels as active Discovered tunnels that have been activated by whatever was running before us stay in TB_TUNNEL_INACTIVE until hibernation restore such that anything depending on tb_tunnel_is_active() skips them. Mark them active during discovery instead. These now also emit TUNNEL_EVENT=activated uevents during discovery.
