Subjectptrace question
I have a question on the ptrace system call

In kernel/ptrace.c in the function access_one_page(),
why is read access denied to pages which are
marked PG_reserved ?

I have some pages in my driver which are reserved
and memory mapped to user applications which I'd
like to access in gdb.

Any clues to what is the risk if I were to enable
accessing of pages which are marked "reserved"

Thanks in advance !
