Subject: [PATCH v3 2/3] virtio_pci_legacy: drop callback sync on reset
Date: Fri, 11 Sep 2026 17:20:18 -0400	[thread overview]
Message-ID: <572661b65eebb784652e5843944d284bbceb2954.1789160982.git.mst@redhat.com> (raw)
In-Reply-To: <cover.1789160982.git.mst@redhat.com>

The virtio core now synchronizes callbacks after reset,
so the legacy PCI transport no longer needs to do it itself.

Assisted-by: LLM
Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Changes v2->v3: split from v2 patch 2 (legacy part only)
