Subject: Add --post-script to tap-driver.sh
X-Git-Tag: v2.11.0-rc1~302
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=bce066c49dc7413a1cb3d8df0ea829990b494202;p=lttng-tools.git

Add --post-script to tap-driver.sh

Allow warn_process.sh to be run between each test to validate that a
test does not leave ghost processes.
