I am not sure how the rcu_scheduler_active changes in __synchronize_srcu work,
but there seem to be a few problems in them. First,
"if (done && likely(!driving))" on line 453 doesn't appear to ever happen,
as driving doesn't get set to false when srcu_reschedule is called. This seems
like it could

This also happened on x86 a few times during fuzzing, however it
wasn't reproducible.
