- The no-op I/O scheduler is a minimal scheduler that does basic merging
- and sorting. Its main uses include non-disk based block devices like
- memory devices, and specialised software or hardware environments
- that do their own scheduling and require only minimal assistance from
- the kernel.

-config IOSCHED_DEADLINE

- default y
- ---help---
- The deadline I/O scheduler is simple and compact. It will provide
- CSCAN service with FIFO expiration of requests, switching to
- a new point in the service tree and doing a batch of IO from there
- in case of expiry.

- The CFQ I/O scheduler tries to distribute bandwidth equally

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
