+ MQ version of the deadline IO scheduler.
+
+config MQ_IOSCHED_KYBER
+ tristate "Kyber I/O scheduler"
+ default y
+ help
+ The Kyber I/O scheduler is a low-overhead scheduler suitable for
+ multiqueue and other fast devices. Given target latencies for reads and
+ synchronous writes, it will self-tune queue depths to achieve that
+ goal.

+ help
+ BFQ I/O scheduler for BLK-MQ. BFQ distributes the bandwidth of
+ of the device among all processes according to their weights,
+ regardless of the device parameters and with any workload. It
+ also guarantees a low latency to interactive and soft
+ real-time applications. Details in
+ Documentation/block/bfq-iosched.rst

+ Enable hierarchical scheduling in BFQ, using the blkio
+ (cgroups-v1) or io (cgroups-v2) controller.

+config BFQ_CGROUP_DEBUG
+ bool "BFQ IO controller debugging"
+ depends on BFQ_GROUP_IOSCHED
+ help
+ Enable some debugging help. Currently it exports additional stat
+ files in a cgroup which can be useful for debugging.
