sched_ext: Bypass BPF scheduler while PM events are in progress
PM operations freeze userspace. Some BPF schedulers have active userspace component and may misbehave as expected across PM events. While the system is frozen, nothing too interesting is happening in terms of scheduling and we can get by just fine with the fallback FIFO behavior. Let's make things easier by always bypassing the BPF scheduler while PM events are in progress. Signed-off-by: Tejun Heo <[email protected]> Reviewed-by: David Vernet <[email protected]>
