Subject: Fix health check: signal parent before exit testpoint
X-Git-Tag: v2.5.0-rc1~254
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=72453c8c97897cb5b5e0aabcbd42a8994fab66b2;p=lttng-tools.git

Fix health check: signal parent before exit testpoint

We need to signal parent for readiness before hitting the thread exit
testpoint, otherwise we hang the test.
