Subject: why so many unexported headers checking __KERNEL__?

  as an unintended side effect of checking for proper exporting to
user space and unifdef'ing, i noticed that there are literally
hundreds of kernel header files that check the value of __KERNEL__ in
some way, but are never exported to user space.  what's the point of
that?  thanks.
