Help writing kernel module...

[Ryan Hope]

I can't find any information on how to make a kernel module load
another module. Can someone please tell me how to do this? Thanks in
advance.

Use a symbol exported by that other module and your module should
automatically depend on that module and modprobe will nicely load it
before your module for you.

what about if I want to determine if a module is loaded?

Don't know.  Of course really why would you care if a module of a
certain name is loaded.  You should only care that a module providing
the function you want is loaded.

Perhaps you need to explain what you are trying to do.
