And in some serial line disciplines line ppp and slip...

Anyway, tty.h looks like a good place for this.
But, seeing these global 64-bit counters incremented here and
there, some MP-safety bell rings.
How about putting the counters into the individual tty structs,
where they are protected by a lock?
The status querying sysctl / kvm grovelers would have to add
them up then.
