I have a question on the ptrace system call implementation:
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 ! Rajeev
