"Change enc_status_change_finish() too... "

"Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
to do frotz", as if you are giving orders to the codebase to change
its behaviour."

You should know this by now...

Another thing you should long know by now: get_maintainer.pl. You do
know that when you send a patch which touches multiple different
"places", you run it through get_maintainer.pl to get some hints as to
who to CC, right?

Because you're touching HyperV code and yet none of the HyperV folks are
CCed.

Do I need to give you the spiel I give to kernel newbies? :)

Lemme Cc them for you now.
