Subject: Fix: Don't (re)define STAP_PROBEV
X-Git-Tag: v2.7.1~5
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=f018237c0b19ca18ac95d1584e3acd5602d666eb;p=lttng-ust.git

Fix: Don't (re)define STAP_PROBEV

Define a new LTTNG_STAP_PROBEV macro to avoid clobbering STAP_PROBEV or
emitting unwanted sdt probes when lttng-ust has been built without sdt
support.
