Wouldn't that be lot of the same issues as a "swapoff" with some
portion of that in use? (except for the kernel data case of
course...)
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
