Hello!


On slide 39 it is stated that for the shared kernel memory region there
is one master page directory that is updated and lazily copied to all AS
on demand.

While this works for right promotions what about demotion/deletion, e.g.
deallocation of kernel pages? Does Fiasco never free pages it once
allocated?



Thanks, Jan.
