swap_out() will deactivate everything it finds to be not-recently used, and that's how the inactive list ends up getting replenished.
But if you want to put an unconditional "refill_inactive()" after the inactive shrink failed, just to work with the case of the active list having a lot of interesting pages. That's not a mapped vs unmapped issue, that's more a "maybe all the DMA pages are on the active list" kind of thing.
