Subject: [RESEND PATCH 0/2] sched/fair: Add documentation and optimize __update_sched_avg()

Hi Peter,

I found I have some patches that go nowhere, out of which two stand out. So I resend them.

The first one adds a document about how to calculate the constants used in load tracking,
which was suggested by you and mentioned in commit 7b20b916e953cabef569541f991a0a583bc344cb

      sched/fair: Optimize sum computation with a lookup table

And the second one attempts to optimize __update_sched_avg(), mostly resulting in code simplification.

These two patches have NO changes made to the names nor functions in the existing codes.

Would you please give it a look?

Thanks,
Yuyang
