BTW: Matthew you yourself have said that after a page-load of memcpy
a user should call sched otherwise bad things will happen to the system
you even commented so on one of my patches when you thought I was
allowing a single memcpy bigger than a page.

So if the user *must* call sched after a call to ->direct_access that
is a "sleep" No?

Thanks
