Subject: Tracepoint API namespacing '__probe_desc'
X-Git-Tag: v2.13.0-rc1~42
X-Git-Url: http://git.lttng.org/?p=lttng-ust.git;a=commitdiff_plain;h=c9201081eda56bee10254f8df7a1c7db0fd023de

Tracepoint API namespacing '__probe_desc'

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.
