Hi,

To be more precise, there's a single call to c->trans_mode->cancelled in
net/9p/client.c, in p9_client_flush, which is called on subfunction returning
-ERESTARTSYS... which never happens as far as I could see.

This will be useful once/if we start working on client recovery, though
- so the function in itself definitely does interest me, and I guess
that thinking about I would have preferred to have the hook added rather
than the function removed.
But there definitely is no hurry to add this cancelled function till
then.

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:

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 :)
