Subject: [PATCH v2 11/32] selftests/ftrace: Use loopback address instead of localhost
Date: Fri, 17 Aug 2018 01:34:23 +0900	[thread overview]
Message-ID: <153443726327.23257.3638322755203446041.stgit@devbox> (raw)
In-Reply-To: <153443695002.23257.13628220023468200991.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.
