config MQ_IOSCHED_KYBER
	tristate "Kyber I/O scheduler"
	default y
	---help---

	  multiqueue and other fast devices. Given target latencies for reads and
	  synchronous writes, it will self-tune queue depths to achieve that
	  goal.

config IOSCHED_BFQ

	---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
