The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

The sysfs filesystem is a virtual filesystem that the kernel uses to
|
|
export internal kernel objects, their attributes, and their
|
|
relationships to one another.
|
|
|
|
Users can use sysfs to ascertain useful information about the running
|
|
kernel, such as the devices the kernel has discovered on each bus and
|
|
which driver each is bound to. sysfs can also be used to tune devices
|
|
and other kernel subsystems.
|
|
|
|
Some system agents rely on the information in sysfs to operate.
|
|
/sbin/hotplug uses device and object attributes in sysfs to assist in
|
|
delegating policy decisions, like persistently naming devices.
|
|
|
|
sysfs is currently used by the block subsystem to mount the root
|
|
partition. If sysfs is disabled you must specify the boot device on
|
|
the kernel boot command line via its major and minor numbers. For
|
|
example, "root=03:01" for /dev/hda1.
