According to KTAP specification[1], results should always start from a
header that provides a TAP protocol version, followed by a test plan with
a count of items to be executed. That pattern should be followed at each
nesting level. In the current implementation of the top-most, i.e., test
suite level, those rules apply only for test suites built into the kernel,
executed and reported on boot. Results submitted to dmesg from kunit test
modules loaded later are missing those top-level headers.
As a consequence, if a kunit test module provides more than one test suite
then, without the top level test plan, external tools that are parsing
dmesg for kunit test output are not able to tell how many test suites
should be expected and whether to continue parsing after complete output
from the first test suite is collected.
Submit the top-level headers also from the kunit test module notifier
initialization callback.
v3: Fix new name of a structure moved to kunit namespace not updated in
executor_test functions (lkp@intel.com).
v2: Use kunit_exec_run_tests() (Mauro, Rae), but prevent it from
emitting the headers when called on load of non-test modules.
