Hi.
Found this building bproc. New O(1) scheduler kills the nice field in
task struct. It gives a way to fix the niceness (set_user_nice()), but
the funtion to _query_ is not exported. Any particular reason ?

Probably because Ingo intended to hide as many interfaces to the
scheduler as possible and only export those symbols that were needed.
It is safe to export if it is needed.

Seems kind of silly to be able to set it but not read it...
