  "message": "ftrace: printk and trace irqsoff and wakeups\n\nprintk called from wakeup critical timings and irqs off can\ncause deadlocks since printk might do a wakeup itself. If the\ncall to printk happens with the runqueue lock held, it can\ndeadlock.\n\nThis patch protects the printk from being called in trace irqs off\nwith a test to see if the runqueue for the current CPU is locked.\nIf it is locked, the printk is skipped.\n\nThe wakeup always holds the runqueue lock, so the printk is\nsimply removed.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
