From: Michael Jeanson Date: Thu, 22 Apr 2021 16:18:57 +0000 (-0400) Subject: Move dynamic-type to libcommon X-Git-Tag: v2.13.0-rc1~12 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=f78f3df1b255162d62a68f31aba34b86528a029f;p=lttng-ust.git Move dynamic-type to libcommon It is used by both liblttng-ust and liblttng-ust-ctl and contains no shared state.
