From f0c42a65633341ad048718c7a6dbd035818e9eaf Mon Sep 17 00:00:00 2001
From: Richard Purdie <richard.purdie@linuxfoundation.org>
Date: Thu, 4 Apr 2019 14:20:31 +0100
Subject: [PATCH 2/3] use process groups when spawning
Rather than just killing the process we've swawned, set the process group
for spawned children and then kill the group of processes.
Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
Upstream-Status: Pending [code being tested]
