Lines Matching full:priority

3  * Block rq-qos policy for assigning an I/O priority class to requests.
5  * Using an rq-qos policy for assigning I/O priority class has two advantages
24  * enum prio_policy - I/O priority class policy.
25  * @POLICY_NO_CHANGE: (default) do not modify the I/O priority class.
29  * @POLICY_ALL_TO_IDLE: change the I/O priority class into IOPRIO_CLASS_IDLE.
153 		 * For RT threads, the default priority level is 4 because  in blkcg_set_ioprio()
154 		 * task_nice is 0. By promoting non-RT io-priority to RT-class  in blkcg_set_ioprio()
156 		 * RT-class but need a higher io-priority can use ioprio_set()  in blkcg_set_ioprio()
165 	 * Except for IOPRIO_CLASS_NONE, higher I/O priority numbers  in blkcg_set_ioprio()
166 	 * correspond to a lower priority. Hence, the max_t() below selects  in blkcg_set_ioprio()
167 	 * the lower priority of bi_ioprio and the cgroup I/O priority class.  in blkcg_set_ioprio()
168 	 * If the bio I/O priority equals IOPRIO_CLASS_NONE, the cgroup I/O  in blkcg_set_ioprio()
169 	 * priority is assigned to the bio.  in blkcg_set_ioprio()
