Subject: [PATCH v3 1/6] x86/hyperv: Rename guest crash shutdown function
Date: Mon, 6 Oct 2025 15:42:03 -0700 [thread overview]
Message-ID: <20251006224208.1060990-2-mrathor@linux.microsoft.com> (raw)
In-Reply-To: <20251006224208.1060990-1-mrathor@linux.microsoft.com>
Rename hv_machine_crash_shutdown to more appropriate
hv_guest_crash_shutdown and make it applicable to guests only. This
in preparation for the subsequent hypervisor root crash support
patches.
