why null kernel module? why kernel listed in kldstat?

["Jeremy C. Reed" <reed@xxxxxxxxxxxxx>]

Why would someone use "null" kernel module?

Is "nullfs" same as "null"? If so, how is loader configuration called 
nullfs_load while file is null.ko?

I see a system that has "null" listed by kldstat but nullfs_load is NO (by 
default).

Why is kernel also listed in kldstat output?
