This patch optimizes the enqueue and dequeue of rt_se, the strategy employs
a bottom-up removal approach. Specifically, when removing an rt_se at a
certain level, if it is determined that the highest priority of the rq
associated with that rt_se has not changed, there is no need to continue
removing rt_se at higher levels. At this point, only the total number
of removed rt_se needs to be recorded, and the rt_nr_running count of
higher-level rq should be removed accordingly.

1474 /*
1475 * To optimize the enqueue and dequeue of rt_se, this strategy employs a
1476 * bottom-up removal approach. Specifically, when removing an rt_se at a
1477 * certain level, if it is determined that the highest priority of the rq
1478 * associated with that rt_se has not changed, there is no need to continue
1479 * removing rt_se at higher levels. At this point, only the total number
1480 * of removed rt_se needs to be recorded, and the rt_nr_running count of
1481 * higher-level rq should be removed accordingly.
1482 *
1483 * For enqueue operations, if an rt_se at a certain level is in the rq,
1484 * it is still necessary to check the priority of the higher-level rq.
1485 * If the priority of the higher-level rq is found to be lower than that
1486 * of the rt_se to be added, it should be removed, as updating the highest
1487 * priority of the rq during addition will cause the rq to be repositioned
1488 * in the parent rq.
1489 *
1490 * Conversely, for dequeue operations, if an rt_se at a certain level is
1491 * not in the rq, the operation can be exited immediately to reduce
1492 * unnecessary checks and handling.
1493 *
1494 * The return value refers to the last rt_se that was removed for enqueue
1495 * operations. And for dequeue operations, it refers to the last rt_se
1496 * that was either removed or had its rt_nr_running updated.

1474 /*
1475 * To optimize the enqueue and dequeue of rt_se, this strategy employs a
1476 * bottom-up removal approach. Specifically, when removing an rt_se at a
1477 * certain level, if it is determined that the highest priority of the rq
1478 * associated with that rt_se has not changed, there is no need to continue
1479 * removing rt_se at higher levels. At this point, only the total number
1480 * of removed rt_se needs to be recorded, and the rt_nr_running count of
1481 * higher-level rq should be removed accordingly.
1482 *
1483 * For enqueue operations, if an rt_se at a certain level is in the rq,
1484 * it is still necessary to check the priority of the higher-level rq.
1485 * If the priority of the higher-level rq is found to be lower than that
1486 * of the rt_se to be added, it should be removed, as updating the highest
1487 * priority of the rq during addition will cause the rq to be repositioned
1488 * in the parent rq.
1489 *
1490 * Conversely, for dequeue operations, if an rt_se at a certain level is
1491 * not in the rq, the operation can be exited immediately to reduce
1492 * unnecessary checks and handling.
1493 *
1494 * The return value refers to the last rt_se that was removed for enqueue
1495 * operations. And for dequeue operations, it refers to the last rt_se
1496 * that was either removed or had its rt_nr_running updated.
