Subject: [PATCH hyperv-next v4 10/16] Drivers: hv: Rename the SynIC enable and disable routines
Date: Mon, 14 Jul 2025 15:15:39 -0700 [thread overview]
Message-ID: <20250714221545.5615-11-romank@linux.microsoft.com> (raw)
In-Reply-To: <20250714221545.5615-1-romank@linux.microsoft.com>
The confidential VMBus requires support for the both hypervisor
facing SynIC and the paravisor one.
Rename the functions that enable and disable SynIC with the
hypervisor. No functional changes.
