Do you think we could change __pskb_pull_tail() right away and fix the
few places that would break, or should we add various helpers with extra
parameters to take a safe route ?

It should always be safe as long as we see no socket attached on RX,
right?

That's the only real case where truesize adjustments can cause trouble.
