Sorry for the delay. I was trying to fix the inaccuracy when normal
and SCHED_FLAG_RECLAIM tasks are present. Its a bit complicated than
I initially thought as Umax_reclaim and Uextra needs to be computed
at the root domain level and this would mean more locking. I have a
patch ready but I think I need to do more testing to understand the
performance implications and it is better to batch it as a separate
series.

So, I am just sending out the GRUB equation fix which is tested well
and I am confident about. Will send out rest of the fixes later as
a separate series.

Thanks,
Vineeth
