From: Michael Jeanson Date: Wed, 21 Apr 2021 21:44:07 +0000 (-0400) Subject: Tracepoint API namespacing ctf_enum X-Git-Tag: v2.13.0-rc1~27 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=78684808fe09e0a094a75042e4f4383b2346bce6;p=lttng-ust.git Tracepoint API namespacing ctf_enum The ABI bump gives us the opportunity to namespace all public symbols under the 'lttng_ust_' prefix. Namespace all API symbols and macros under 'lttng_ust_' / 'LTTNG_UST_' and add compat macros to keep compatibility with the previous API.
