Subject: [PATCH] virtio_vdpa: Support surprise removal of virtio vdpa device
Date: Tue, 11 Jan 2022 12:08:31 +0800 [thread overview]
Message-ID: <20220111040831.5224-1-lidongsheng@dayudpu.com> (raw)
When virtio vdpa device removed, the abnormal damage of the device cannot be
perceived normally, which will cause problems similar to:
Commit 43bb40c5b926 ("virtio_pci: Support surprise removal of
virtio pci device")
Hence, add the ability to abort the command on surprise removal
