Yep, but applying the v2 patch, and then building the headers,
followed by copying hyperv.h from the output to /usr/include/linux
makes it build fine. :-)

Subject: [PATCH] Adding hyperv.h to uapi headers
This patch adds the hyperv.h header to the uapi folder, and adds it to the
Kbuild
file.
Doing this enables compiling userspace Hyper-V tools using the installed
headers.
Not all of the contents hyperv.h is needed for users-space programs.
I would not ack this patch.
I agree, but is the v2 better?

Yep, but applying the v2 patch, and then building the headers,

makes it build fine. :-)

Subject: [PATCH] Adding hyperv.h to uapi headers
This patch adds the hyperv.h header to the uapi folder, and adds it to the
Kbuild
file.
Doing this enables compiling userspace Hyper-V tools using the installed
headers.
Not all of the contents hyperv.h is needed for users-space programs.
I would not ack this patch.
