Mathieu Desnoyers c496fdc3c6 futex: Fix futex_waitv() hrtimer debug object leak on kcalloc error ... commit 94cd8fa09f upstream. In a scenario where kcalloc() fails to allocate memory, the futex_waitv system call immediately returns -ENOMEM without invoking destroy_hrtimer_on_stack(). When CONFIG_DEBUG_OBJECTS_TIMERS=y, this results in leaking a timer debug object.
