Either use gdb YOUR_VMLINUX and disassemble mem_cgroup_handle_oom or
use objdump -d YOUR_VMLINUX and copy out only mem_cgroup_handle_oom
function.

If 'YOUR_VMLINUX' is supposed to be my kernel image:

You need vmlinux not vmlinuz...

ok, got it but still no luck:

# objdump -d vmlinux | grep mem_cgroup_handle_oom
<no output>


i can recompile the kernel if anything needs to be added into it.
