-config IOSCHED_NOOP
- 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_AS
- tristate "Anticipatory I/O scheduler"
- default y
- ---help---
- The anticipatory I/O scheduler is the default disk scheduler. It is
- generally a good choice for most environments, but is quite large and
- complex when compared to the deadline I/O scheduler, it can also be
- slower in some cases especially some database loads.
-
-config IOSCHED_DEADLINE
- tristate "Deadline I/O scheduler"
- default y
- ---help---
- The deadline I/O scheduler is simple and compact, and is often as
- good as the anticipatory I/O scheduler, and in some database
- workloads, better. In the case of a single process performing I/O to
- a disk at any one time, its behaviour is almost identical to the
- anticipatory I/O scheduler and so is a good choice.
-
-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
- working environment, suitable for desktop systems.

- prompt "Default I/O scheduler"
- default DEFAULT_AS
- help
- Select the I/O scheduler which will be used by default for all
- block devices.
