Hello everyone,
I am a learing device drivers. So far I've executed small modules. I was wondering how linux allows insertion of a module even while its running? I did a search for it but not satisfied or may be could not understand. All I got is linux daemon executes modprobe add new module. But my question is how this happen? The kernel is in execution already. How does the new executable file gets attached to the running kernel?
Thanks.
