HI Daniel,
Isn't the only scenario where another cpu can put an idle task on our runqueue,
Well, I am not sure to understand what you meant, but I assume you are asking if it is possible to have a task to be pulled when we are idle, right ?
This patch fixes the race when the current cpu is *about* to enter idle when calling schedule().
Preeti said the she didn't see a possible to insert a task on the cpu.
I also did a quick check, maybe task come from wakeup path?
