Log Message:
PR kern/48044: panic: kernel diagnostic assertion "uvmexp.swpgonly + npages <=
uvmexp.swpginuse" failed
swpgonly is updated asynchronously with regard to swap use. We can't assert
this condition with confidence in the post-5.0 world, at least not without
broader changes. swpgonly's ultimate use is of a heuristic nature so this
is no problem at all.
