You can add to any file or can add new files also. This depends, where your functions have a best match. 2) and if i am using some variables in that function local to it does it require to add its entry and if yes where? and if variable is to be exported that is global then what? Local variables don't require anything. Global variable can be exported to other modules by EXPORT_SYMBOL macro. 3) how to solve unresolved symbol error? Either you have not defined the symbol or use EXPORT_SYMBOL. 4)i want to ask when i compile a new kernel image from installed kernel source /usr/src/linux-2.4.20-8/ it create linux-2.4.20-8custom kernel version. why it takes that version number and not same linux-2.4.20-8?
