Subject: [PATCH 10/25] selftests/ftrace: Use loopback address instead of localhost
Date: Fri, 27 Jul 2018 21:14:40 +0900	[thread overview]
Message-ID: <153269368036.3084.11089045823444073169.stgit@devbox> (raw)
In-Reply-To: <153269339575.3084.16279591141931053689.stgit@devbox>

Use raw loopback address instead of localhost, because
"localhost" can depend on nsswitch and in some case
we can not resolve the localhost.
