Hi, Here are patches for making sure the ftracetest testcases are checkbashisms clean. This actually needs a patch from Juerg, "selftests/ftrace: Make the coloring POSIX compliant" to complete the work. http://lkml.kernel.org/r/20190220161333.28109-1-juergh@xxxxxxxxxxxxx (Note that this is still under development) So as Juerg pointed, recently ftracetest becomes not POSIX compliant, and such kind of issues happened repeatedly. To avoid those anymore, I decided to introduce a testcase which runs checkbasisms on ftracetest and its testcases. I think this can help us to find out whether it was written in a way out of POSIX.
