ARRAY_SIZE?

Well, I think ARRAY_SIZE is useful to derive the number of 
elements from a static array of the type:

  static const int array[] = { 1, 2, 3, 4, }

but not if its declared as:

  static array[MAXDEV]:

... or have I missed something?

Yes - if you use ARRAY_SIZE() then someone reading the code
doesn't need to find the array definition to ensure the loop
upper bound is correct.
