Debugging Loadable Modules

In order to debug a loaded module, we need to tell the debugger where the module is in memory

The module’s information is not in the vmlinux image because that shows only statically linked drivers

How we proceed depends on where we need to debug

If we need to debug the __init code, we need to set a breakpoint in the sys_init_module() function
