I am ignoring Markus patches and have told him that he should focus on
bug fixes. These patches don't add any value and regularly introduce

That said, "sizeof(*ptr)" is sort of official style. It's slightly
more obvious and easier to review because all the information you need
is on that one line. Also if we change the datatype of ptr then that
format is slightly more future proof.
