This patch-set introduces the possibility of protecting memory that has
been allocated dynamically.  
One thing that jumps out at me as I look at the patch set is: you do not
include any users of this functionality.  Where do you expect this
allocator to be used?  Actually seeing the API in action would be a useful
addition, I think.  
Yes, this is very true.
Initially I had in mind to use LSM hooks as easy example, but sadly they 
seem to be in an almost constant flux.

My real use case is to secure both those and the SELinux policy DB.
I have said this few times, but it didn't seem to be worth mentioning in 
the cover letter.
In general, it is quite hard to merge a new API without users to go along
with it.  Among other things, that's how reviewers can see how well the
API works in real-world use.  I am certainly not the one who will make the
decision on whether this goes in, but I suspect that whoever *does* make
that decision would prefer to see some users.

Thanks,

jon
