From: Michael Jeanson Date: Wed, 21 Apr 2021 15:19:16 +0000 (-0400) Subject: Tracepoint API namespacing tracelog X-Git-Tag: v2.13.0-rc1~36 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=1698631bb3fbab41277b3953e193dd2fd4a74afa;p=lttng-ust.git Tracepoint API namespacing tracelog 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.
