'gate' is not allocated at this point either... at least not in Linus' tree.

And you forgot {} around these 2 statements.

There are no braces around this so the function of this code as written
is an unconditional return and the return shouldn't be indented. I
suspect, without reading the rest of the file, that that isn't what you
intended.

There's a typo in kfree. How does that even compile?

In any case, the kernel is not coded in Python.

C uses braces { } to enclose blocks of code, and does not care about
indentation - indentation is meaningless to C. Python purely identifies
blocks of code by indentation alone.

Please take account of the programming language when creating patches.
