Subject: What does 'if EMBEDDED' mean?

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.

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?
