From 9298dfabd9658315df34616b1e9a10b3579a92bd Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 13 Sep 2013 16:38:59 +0200 Subject: lib: add test for igt_fork_signal_helper If we're really fast we've trying to stop the signal helper again we somehow race somewhere and it'll never happen. So add a testcase for this. Since I expect more to come for testsuite tests add a separate make target for them.
