Sure, the interface remains the same (write 8 bytes), but the
implementation can change. For example, we can implement it to work
from interrupt context, once we hack the locking appropriately.
I was thinking more along the lines of eventfd_signal(). AIO and vbus
currently use this interface, as opposed to the more polymorhpic
f_ops->write().
But eventfd_signal basically marries us to eventfd.
