All the tests listed in kselftest-list.txt are all run every time. This patch enhanced the run_kselftest.sh to make the test collections (or tests) individually selectable. e.g.: $ ./run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep Additionally adds a way to list all known tests with "-l", usage with "-h", and perform a dry run without running tests with "-n".
