  "message": "hrtimer: fix recursion deadlock by re-introducing the softirq\n\nImpact: fix rare runtime deadlock\n\nThere are a few sites that do:\n\n  spin_lock_irq(\u0026foo)\n  hrtimer_start(\u0026bar)\n    __run_hrtimer(\u0026bar)\n      func()\n        spin_lock(\u0026foo)\n\nwhich obviously deadlocks. In order to avoid this, never call __run_hrtimer()\nfrom hrtimer_start*() context, but instead defer this to softirq context.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
