Yes, of course.

I have rebased v19 to the latest v4.10-rc3-e96f8f1, it dosen't need
any modification.
I will rebase it every day, and will repost it if it need any  modification.

But for now, V19 works well with the master branch of upstream kernel.
Do I need to re-post it even if it doesn't need any improvement or
modification? :-)
