What does 'if EMBEDDED' mean?

What does 'if EMBEDDED' mean?

[jidong xiao]

For example,

config SYSFS
        bool "sysfs file system support" if EMBEDDED
        default y

What does 'if EMBEDDED' mean?Can I choose n here?
I saw there is no corresponding option within `make menuconfig`, so I
am wondering what can I do if I wanna to disable this option, directly
change
"default y" to "default n" in the Kconfig file?

Thanks
Jason

The "if EMBEDDED" means that you only see this question if 
CONFIG_EMBEDDED=y.

Otherwise, the default is used without the question being asked.

  General setup
    Configure standard kernel features (for small systems)

Thank you, Adrian, it's very clear.

By the way, can sysfs be compiled as a module?Does bool type mean this
option cannot be compiled as a module?

"bool" means it can't be compiled as a module.

Why do you want to compile it as a module?
