From: Michael Jeanson Date: Fri, 12 Mar 2021 19:04:44 +0000 (-0500) Subject: Move context types to private header X-Git-Tag: v2.13.0-rc1~276 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=fa194c4157f029404fe2ea10098d1bbcebcf6aa9;p=lttng-ust.git Move context types to private header This is an API change but the major SONAME bump to '1' gives us the opportunity to hide symbols that should have been private from the start.
