I've just looked at the code in uvm_swap_stats().
Might be easier to either clone the entire loop, or pass in a helper
function which is passed the 'sdp' and 'inuse' fields.
Even for the 'normal' case that would save copying the pathname twice.
It isn't as though a lock is released before the copyout.
The read lock is held throughout.
