60 * @brief This file contains all of method prototypes and type
61 * definitions specific to the high priority request queue (HPRQ).
62 * The HPRQ is the mechanism through which internal requests or
63 * other important requests created by the framework are stored.
64 * The HPRQ is checked during the scif_controller_start_io() path
65 * and is given precedence over user supplied IO requests.
66 * Additionally, when requests are created there is an attempt to
