struct_size() is more correct than array_size(). If there were really
a danger from array overflows then array_size() would not prevent it
There should probably be a static checker warning for when people do
"expr + array_size()". If you're looking for something to write, that's
an idea you could implement with Coccinelle or Smatch.
