It's an interesting point...

At one point Smatch didn't track static variables and it used to
generate occasional false positives.  And it's like you say, those
little "static" qualifiers are hard to spot in a wall of declaration
text.  I've never considered moving the declarations out of the
function scope but it might be a good idea?

But in this case since this data is const, the static vs not-static
doesn't affect flow analysis or readability.
