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.
