Your systemtap.exp changes look all wrong to me.
Please explain their rationale.

Yes, I had not noticed that there is now a src/testsuite/sys/sdt.h. I'll change systemtap.exp back.


Your addition of _SDT_SEMAPHORE... I thought we had abandoned the semaphore thing,

The implementation is unchanged; I changed the name to match the pattern in sdt.h. Nothing sacred about the name or implementation; we can certainly change it. The semaphore mechanism is used to implement the *_ENABLED mechanism, the usefulness of which is described by Mark here:
