What you are suggesting, if I have understood it correctly, is that,
when the pool is protected, the addresses already given out, will become
traps that get resolved through a lookup table that is built based on
the content of each allocation.
That seems to generate a lot of overhead, not to mention the fact that
it might not play very well with the MMU.
That is effectively what i'm suggesting - as a form of protection for
consumers against direct reads of data which may have been corrupted
by some irrelevant means. In the context of pmalloc, it would probably
be a separate type of ro+verified pool
ok, that seems more like an extension though.
ATM I am having problems gaining traction to get even the basic merged :-)
I would consider this as a possibility for future work, unless it is
said that it's necessary for pmalloc to be accepted ...
