What about the !PREEMPT_RT case.. It still wouldn't disable interrupts in the below..
- local_irq_save(flags); if (up->port.sysrq) { /* serial8250_handle_port() already took the lock */ locked = 0; } else if (oops_in_progress) { - locked = spin_trylock(&up->port.lock); + locked = spin_trylock_irqsave(&up->port.lock, flags); } else - spin_lock(&up->port.lock); + spin_lock_irqsave(&up->port.lock, flags);
