| H A D | hrtimer.h | diff 887d9dc989eb0154492e41e7c07492edbb088ba1 Thu Jun 11 07:46:48 CDT 2015 Peter Zijlstra <peterz@infradead.org> hrtimer: Allow hrtimer::function() to free the timer
Currently an hrtimer callback function cannot free its own timer
because __run_hrtimer() still needs to clear HRTIMER_STATE_CALLBACK
after it. Freeing the timer would result in a clear use-after-free.
Solve this by using a scheme similar to regular timers; track the
current running timer in hrtimer_clock_base::running.
