If we only use the PAIR_PRIVATE_SIZE here, maybe we can put the
define in this file too, rather than in the header file.

And could fit 80 characters:

+       pair = kzalloc(sizeof(*pair) + PAIR_PRIVAT_SIZE, GFP_KERNEL);

I will use a function pointer
    int (*get_pair_priv_size)(void)

Since it's the size of pair or cts structure, could be just a
size_t variable?
