Sebastian Andrzej Siewior 73d20564e0 hrtimer: Don't dereference the hrtimer pointer after the callback ... A hrtimer can be released in its callback, but lockdep_hrtimer_exit() dereferences the pointer after the callback returns, i.e. a potential use after free. Retrieve the context in which the hrtimer expires before the callback is invoked and use it in lockdep_hrtimer_exit().
