kcsan: test: Defer kcsan_test_init() after kunit initialization
When the test is built into the kernel (not a module), kcsan_test_init() and kunit_init() both use late_initcall(), which means kcsan_test_init() might see a NULL debugfs_rootdir as parent dentry, resulting in kcsan_test_init() and kcsan_debugfs_init() both trying to create a debugfs node named "kcsan" in debugfs root. One of them will show an error and be unsuccessful. Defer kcsan_test_init() until we're sure kunit was initialized. Signed-off-by: Marco Elver <[email protected]> Signed-off-by: Paul E.
