From: Christian Babeux Date: Tue, 14 May 2013 21:53:45 +0000 (-0400) Subject: Tests: Move the babelstats utility to tests/utils X-Git-Tag: v2.2.0-rc3~65 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=9d806fbf7a6806b79cfddba58ced01441c1bf188;p=lttng-tools.git Tests: Move the babelstats utility to tests/utils This utility will prove useful in trace validation for other tests, so put it in a common location accessible by the tests.
