How to unwind kernel stack to seek for specific caller?

[Lev Olshvang]

Hello all linuxers,


I am writing a LSM kernel module which had register  hook to mmap()

I need to know whether this call came from elf loader or other code path.

I know that I can print stack of function using dump_stack(), in this case I should 
seek within kmsg buffer.

I see that kmsg_dump_get_buffer() function can get kernel messages but it is mot clear for me how I can get parameters 
of this functions

Regards,
Lev
