Some minimal user land executables to run tests and to enable/disable
coverage:
ktfrun: Simple generic test runner for generic ktf tests
ktftest: A test runner for the ktf selftests. Contains code to
configure specific selftest context objects.
ktfcov: A utility to selectively enable coverage support for
a kernel module. Coverage support can also be enabled
in code by tests, if desired.
hybrun: A test that implements a hybrid test runner.
hybrid.cc: User mode part of the hybrid_self
ktfrun.cc: Generic user level application to run kernel tests
