Peter, is there a reason that task_nice() is not a static inline in
sched.h and have these macros there too? They only reference fields in
task_struct that are already defined there. I don't see why they need
to be private to kernel/sched.
Agree. These macros are useful to other modules out of kernel/sched.
But they are private to kernel/sched currently.
And the floodgates open.. _why_ would a module care about nice values?
That's sounds just so full of wrong.

Sorry for my misnomer with 'modules'. Actually I mean other subsystems in
kernel, such as trace, sched, rcu. :)

I did not mean the module for modprobe.

Sorry for my terrible expression :(.
