Hi!

+Testing +------- + +A new system call should obviously be tested; it is also useful to provide +reviewers with a demonstration of how user space programs will use the system +call. A good way to combine these aims is to include a simple self-test +program in a new directory under tools/testing/selftests/.
I know that this is a bit off topic, but since the selftest is now the official place to add kernel testcases to let me rant about it a bit. It's a bit of a pain seeing people reinvent the wheel and trying to figure out consistent test interface while most of the problems has been solved in LTP[1] test library quite some time ago. Especially use of the SAFE_MACROS[2] would simplify writing test setups quite a lot. I wonder if we can at least share the test library, pulling it out of LTP, or at least the interesting parts, wouldn't be hard at all.
