Hi Luca,

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
