Wouldn't that be lot of the same issues as a "swapoff" with some

No. Swapoff makes pages allocated to userland applications in swap
move back into main memory -- this is much easier because:

- the pages are on disk, we _know_ the aren't locked my mlock or
pinned for IO (kiobufs, whatever)

- there are no kernel pages/buffers in this area, even harder than
the above to deal with
