Hi all,

I noticed CONFIG_BASE_SMALL in different parts
of the kernel code, with ifdef/ifndef.
I wonder what does CONFIG_BASE_SMALL mean?
And how can I configure it, e.g. through make menuconfig?

thanks,

Yeah, here:

init/Kconfig:
....
config BASE_SMALL
int
default 0 if BASE_FULL
default 1 if !BASE_FULL
....
config BASE_FULL
default y
bool "Enable full-sized data structures for core" if EMBEDDED
help
Disabling this option reduces the size of miscellaneous core
kernel data structures. This saves memory on small machines,
