Great, glad there is already a fix under review.

When I try out the patch the application does not compile. The error
messages are the same as without the patch because _LTTNG_SDT_PROBE() is
not defined. Was that supposed to be _SDT_PROBE() instead?

The application compiles successfully after replacing _LTTNG_SDT_PROBE()
with _SDT_PROBE().
