I write a kernel module which has initialize and end function. I want one more function and want to call it from the user space process at any time i want.
Is it applicable ? If so, how ?
I am working on CentOS 5.2 and custom kernel, patched from linux 2.6.18.
EDIT: To make clear, I want to write a function into kernel module and call this function from the regular source.c file.
