As Arjan said - what you probably want to be doing instead is changing the code in your first module that provides the bufproc_* functions so that they're wrappers around some code that does the "real work", and then call the real_work function from your second module. Most likely, what you *really* want to be passing around is some 'struct *foo', and the bufproc_* functions are converting to/from a struct foo and a linear byte stream. (In the limiting case where it's just one variable, why not just 'EXPORT_SYMBOL(variable)' in the first module and then just assign or read the variable from the second module?)
