EXPORT_SYMBOL_GPL() for this, and all other exports?
And it seems that you have a bunch of "unused" parameters for this, and
other public functions. Please just remove them entirely, otherwise it
just confuses reviewers, and anyone who wants to write code to interface
with the code. You can always add parameters at a later point in time
if you find that you really need them.
