I would prefer to NACK my patch, it messes up things more than
fixes.

If we really want to get rid of this function we should
completely revert this patch:

80b45261a0b263536b043c5ccfc4ba4fc27c2acc

otherwise, spread in the code, there will be empty references to
the 'cancelled' function (struct p9_trans_module in transport.h
and the one you mentioned).

I would rather prefer Paul's approach to mine, let's just get rid
of the warning :)
