| * This module provides a "do nothing" kernel service. |
| * |
| * This service is primarily used by other kernel services that need a way to |
| * resume the execution of a kernel request that could not be completed in a |
| * single invocation of the _k_server fiber. However, it can also be used by |
| * a task to measure the overhead involved in issuing a kernel service request. |
