BTW if we stretch this argument a little bit more, we should also kill the ZERO_OR_NULL_PTR() check from kfree() and make it callers responsibility to perform the checking only if applicable ... we are currently doing a lot of pointless checking in cases where caller would be able to guarantee that the pointer is going to be non-NULL.
