The function name doesn't make any sense.  You don't copy anything
here, but you grab a reference to it.  A better name would be bdgrab,
mirroing the names of functions like igrab.  A kerneldoc comment
documenting it would also be very helpful.

Why do you export it?  The swapfile code is not actually modular.
