Still, it seems weird that we're declaring the `data_race` on > CON_ENABLED but not CON_BOOT ? For my upcoming v3 I decided to drop this patch and will keep the existing direct reading of @flags. Instead of this patch, for v3 the comment will additionally mention why @flags is allowed to be directly read: /* * Hold the console_lock to guarantee that no consoles are * unregistered until the kgdboc_earlycon setup is complete. * Trapping the exit() callback relies on exit() not being * called until the trap is setup. This also allows safe * traversal of the console list and race-free reading of @flags. */ John Ogness
