Thanks!

The hyperv-next tree doesn't have commit 1502b42819c2 [1] that
is already in Linus' tree for the upcoming 7.3-rc1. That commit came
thru the drm tree, which is probably why the hyperv tree doesn't
have it.

What's the best way to proceed? Rebase the hyperv tree on
7.3-rc1 when it comes out a week from now, and then try
applying my patch again? Or is there another approach? Redoing
my patch without commit 1502b42819c2 is just going to create
merge conflicts later on.
