Subject: [PATCH v3 10/28] selftests/ftrace: Use loopback address instead of localhost
Use raw loopback address instead of localhost, because
"localhost" can depend on nsswitch and in some case
we can not resolve the localhost.
Signed-off-by: Masami Hiramatsu <mhiramat@...nel.org>
---
Changes in v3:
- Use $LOCALHOST variable instead of raw loopback address
- Move yield common function into test.d/functions.
