At least aio_bh_schedule_oneshot_full should have the same effect, so should this be done at a lower level, in aio_bh_enqueue() or even aio_notify()?

Not sure about aio_notify. It can operate with different contexts.
Can some of them be not related to the VM state?

All but the main AioContext one would have current_cpu == NULL.

aio_bh_enqueue is better. Moving this code to aio_notify breaks the tests.
