+          If enabled, the static kobject support in Rust will use an atomic
+          variable to check that the kobject has had the appropriate
+          initialization done to it.
+
+          This adds a 32-bit value to each kobject and requires that these kobjects be placed in zero
+          initialized memory. Accesses to the shared variable will invoke an atomic read, and the
+          initializer will have a few atomic operations.
