From: Jérémie Galarneau Date: Thu, 13 Jan 2022 20:38:06 +0000 (-0500) Subject: Tests: add a multi-domain ust+kernel rotation test X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=6f7eb8e1cb829926bcbce2aeb885b0db63fc7af0;p=lttng-tools.git Tests: add a multi-domain ust+kernel rotation test Validate that multi-domain rotations work as intended for both local and remote outputs. This validates the fix introduced by c5c793.
