Subject: [kvm-unit-tests PATCH v5 3/7] s390x: Stop the cpu that is executing exit()
Date: Sat, 1 Feb 2020 10:28:47 -0500 [thread overview]
Message-ID: <20200201152851.82867-4-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200201152851.82867-1-frankja@linux.ibm.com>
CPU 0 is not necessarily the CPU which does the exit if we ran into a
test abort situation. So, let's ask stap() which cpu does the exit and
stop it on exit.
