Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
|
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.

---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.
