No, that doesn't work since it duplicates the path info in the file
name -- something that none of the other kernel/sched/*.c files do.
Do a "ls -1 kernel/sched" to see what I mean if it is not clear.

I honestly didn't spend a lot of time thinking about the file name.
I chose load_avg.c since it had a parallel to the /proc/loadavg that
linux has had since the early 1990s.  I have no real attachment
to that name, but at the same time I'd like to avoid having name
choice become a bikeshedding event...

Thanks,
Paul.
