you need to look closer....for example include/linux/mm.h. There you
will see definition of constants and functions used for memory
management.

So, what library here means IMHO are group of headers that contains
the needed functions/definitions by themselves. Linking? I think it's
better named as "including"...indeed there are linking process during
kernel build, but that is just a way to build final image using
several objects which originated from the practice of refactoring etc.

kindly CMIIW people...
