Note that this was superfluous # before said commit, as back then the hotplug machinery would invoke # init_idle() via idle_thread_get(), which would have already reset the # CPU's idle task's preempt_count to PREEMPT_ENABLED. # # Get rid of this preempt_count write. # # Fixes: f1a0a376ca0c ("sched/core: Initialize the idle task with preemption disabled") # Reported-by: Bharata B Rao #
