[PATCH v3 02/28] selftests/ftrace: Add --console hidden option

From: Masami Hiramatsu
Date: Thu Aug 30 2018 - 10:13:49 EST


Add --console hidden option for debug test cases.

This option allows to put "sh" or something else
when the test case hits a bug.

For example, if you find a testcase which doesn't
pass, you can insert sh for interactive debug as below

-----
#!/bin/sh
# description: sample test case

good-command
suspicious-wrong-command
sh # <- add this for interactive debug
