kernel - need to debug MMAP so where is the object file for MMAP or module containing MMAP() -- how to find in linux?

Question

I am trying to debug MMAP with kprobe but I dont know how to set break points inside MMAP. In my lib/modules there I searched but could not find that resembles mmap containing module. how can I debug mmap with kprobe so I need object file of the routine.

I just need to set breakpoints at different locations. So I could use radare2 for this to view the assembly and check the memory locations which I will specify in KProbe module that will be injected in MMAP function in the routine containing MMAP function, for debugging it.
