Subject: [PATCH v0 1/6] x86/hyperv: Rename guest shutdown functions
Date: Wed, 3 Sep 2025 19:10:12 -0700 [thread overview]
Message-ID: <20250904021017.1628993-2-mrathor@linux.microsoft.com> (raw)
In-Reply-To: <20250904021017.1628993-1-mrathor@linux.microsoft.com>
This commit renames hv_machine_crash_shutdown to more appropriate
hv_guest_crash_shutdown and makes it applicable to guests only. This
in preparation for the subsequent hypervisor root/dom0 crash support
patches.
