- bool
- default y
- ---help---
- 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
- tristate "Deadline I/O scheduler"
- 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.
-
-config IOSCHED_CFQ
- tristate "CFQ I/O scheduler"
- default y
- ---help---
- The CFQ I/O scheduler tries to distribute bandwidth equally
- among all processes in the system. It should provide a fair
- and low latency working environment, suitable for both desktop
- and server systems.
-
- This is the default I/O scheduler.
-
-config CFQ_GROUP_IOSCHED
- bool "CFQ Group Scheduling support"
- depends on IOSCHED_CFQ && BLK_CGROUP
