Subject: [PATCH] Add SerenityOS platform support
|
|
|
|
`fio` abstracts individual operating system support out into to an
|
|
`os/os-<name>.h` header where you can select which platform features
|
|
are available and implement missing function stubs for our operating
|
|
system.
|
|
|
|
This patch implements basic OS support for Serenity just to get fio up
|
|
and running.
