Calling driver functions from kernel space

[Sam Carter <sam.w.carter@xxxxxxxxx>]

Hi all,

I have a char driver/module which compiles and loads into the linux kernel just fine. In this driver are some functions which I would like to access from the kernel file 'fs/readdir.c'. Additionally, how can I test if a driver is loaded?

I need something like the following.

if(myDriver is loaded){

    myDriver.functionCall();
}

All examples I've found on internet searches are doing it from userspace applications.

Thanks for any help
