Subject: [PATCH v3 1/7] x86/hyper-v: move hyperv.h out of uapi
Date:   Fri,  9 Mar 2018 15:02:43 +0100
Message-Id: <20180309140249.2840-2-vkuznets@redhat.com>
In-Reply-To: <20180309140249.2840-1-vkuznets@redhat.com>
References: <20180309140249.2840-1-vkuznets@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

hyperv.h is not part of uapi, there are no (known) users outside of kernel.
We are making changes to this file to match current Hyper-V TLFS and we
don't want to maintain backwards compatibility.

Move the file renaming to hyperv-tlfs.h to avoid confusing it with
mshyperv.h. In future, all definitions from TLFS should go to it and
all kernel objects should go to mshyperv.h or include/linux/hyperv.h.
