SubjectRe: [PATCH 0/6] sched: expel confusing usage of the term "power"
Hi Nico,

Thanks for doing this renaming.
I remember that you asked me to do this while working on cpu_power but
my work has not evolved as fast as expected and as it already implies
some renaming other than s/power/capacity/ i have postponed it to not
make review to complex.

Nevertheless, i can manage the conflicts afterward and rebase my
patches, depending of the review status

Vincent
