Subject: Tracepoint API namespacing '_tp_max_t'
X-Git-Tag: v2.13.0-rc1~49
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=1210ca90e6300ad2dbc271143e14a75355387021;p=lttng-ust.git

Tracepoint API namespacing '_tp_max_t'

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.
