e.g. kobj->sd assignment in sysfs_create_dir() isn't synchronized and doesn't have memory barrier either. Nothing prevents subdirectory creation from accessing half-initialized sysfs_dirent on architectures which require read dependency barriers. The caller is responsible for synchronizing these operations.
