Weizhao Ouyang 32ae8a0669 kfence: defer kfence_test_init to ensure that kunit debugfs is created ... kfence_test_init and kunit_init both use the same level late_initcall, which means if kfence_test_init linked ahead of kunit_init, kfence_test_init will get a NULL debugfs_rootdir as parent dentry, then kfence_test_init and kfence_debugfs_init both create a debugfs node named "kfence" under debugfs_mount->mnt_root, and it will throw out "debugfs: Directory 'kfence' with parent '/' already present!" with EEXIST. So kfence_test_init should be deferred.
