+Subject: [PATCH] rtla: Fix uninitialized variable found
+
+Variable found is not being initialized, in the case where the desired
+mount is not found the variable contains garbage. Fix this by initializing
+it to zero.

+Link: https://lore.kernel.org/all/20230727150117.627730-1-colin.i.king@gmail.com/

+The rtla meta-tool includes a set of commands that aims to analyze
+the real-time properties of Linux. Instead of testing Linux as a black box,
+rtla leverages kernel tracing capabilities to provide precise information
+about the properties and root causes of unexpected results.
