  "message": "rcu: Fix deadlock in TREE_PREEMPT_RCU CPU stall detection\n\nUnder TREE_PREEMPT_RCU, print_other_cpu_stall() invokes\nrcu_print_task_stall() with the root rcu_node structure\u0027s -\u003elock\nheld, and rcu_print_task_stall() acquires that same lock for\nself-deadlock. Fix this by removing the lock acquisition from\nrcu_print_task_stall(), and making all callers acquire the lock\ninstead.\n\nTested-by: John Kacur \u003cjkacur@redhat.com\u003e\nTested-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nLocated-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Paul E.
