Hmm, I think it is just for setting flags, we could reduce some overhead.
For example, a global is used by = and == operator, and '=' sets a value
less than 32 bits.

Keep in mind that SystemTap integers are 64 bits, and atomic_t values are 32
bits on most/all architectures.

That wouldn't work if there are other probe handler users of the same global
that are not reducible to a single atomic_* function call. This one may be
too hard to do right with benefits too small. (We have global statistics
scalars already).
