I'm guessing it's so that all the files that use the scheduler interface
automatically get IS_ERR and PTR_ERR without having to include xen/err.h
directly.
But of course that means files like sched_arinc653.c and sched_credit2.c
end up including xen/err.c even though they don't use those macros.
Would you prefer the other files include it directly instead?
