I see. I think i know what you mean . Your symbol is in kernel address space. I think the mm_struct object you are looking for is init_mm . If so, in the above code I wrote, use pgd_offset_k(addr) instead of pgd_offset(mm, addr). I think that is what you are looking for. Correct me if I misunderstood you.

I see. I think i know what you mean . Your symbol is in kernel address space. I think the mm_struct object you are looking for is init_mm .

Are you sure? Theoritically, kernel address space is mapped throughout
all the task structure (e.g current->mm etc)
After all, if it's a symbol address you're looking for, have you tried
http://lxr.linux.no/linux+v2.6.34/+code=kallsyms_lookup_name and see
if it suits you?
