Integrate optional native KUnit suites with out-of-tree SCST modules. A single CONFIG_SCST_KUNIT_TEST switch includes all test objects of each owner. Declare each suite name and label once and discover source registrations for kunit-list without a build or loaded modules. Preserve ordinary builds without KUnit. Start with a fixed-wire LUN regression. Centralize private visibility and task-scoped static-stub switches, and define retained-fixture reporting for asynchronous tests. Use current native KUnit APIs without compatibility shims. Keep optional execution messages behind CONFIG_SCST_KUNIT_LOG while leaving failure diagnostics unconditional. Add Makefile/Kbuild regression checks and document the shared switch. Keep compatibility builds free of KUnit, including inherited test options and allmodconfig. Generate ordinary in-tree SCST patches with private declarations but without test suites or KUnit build options. Check this boundary and preserve kernels without an unwinder option.
