I'm a little reluctant to suggest that we rename this to might_sleep as
well because it would require that we audit each and every driver to set
this properly, since by default all devices have so far been defaulting
to "might_sleep". But then again, I think that's something that we're
going to need to do at some point anyway.
In the interim, I think we could keep it like this and address this as a
follow-up.
