The changes to the tar script are probably OK. But in general we do not want to exit after the first failure, which is what your changes to the for loops would do. The intention is to build and run as many tests as possible, on as many architectures and machines as possible. So stopping the build because a header or library is missing, or stopping the test run because one test fails, is the exact opposite of what we want to happen. For example a test might fail because it was written for x86 and doesn't work on powerpc, if that caused all my powerpc tests to not run, I would be very unpleased. > It's probably not exhaustive, and > there seem to be some major other deficiencies (e.g., verbose/useless > output during build and run, non-paralle build, shell for-loops sidestep > some normal 'make' behavior). The goals for the kernel selftests are to make it as easy as possible to merge tests, so that as many developers as possible create tests *and* merge them. The current scheme supports that by not imposing much in the way of build system requirements, or standards on what is or isn't appropriate output etc. But if have ideas for improving things while still keeping the requirements on test code low then I'm all ears. cheers -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
