Hi, Could someone help to review it or provide suggestions? Any comments are welcome. This patch is intended to allow the rproc driver to handle the following use-after-free issue: ### UAF log [ 337.540275][ T470] virtqueue_add.llvm.10153462284424984632+0xb48/0 xcc4 [ 337.546969][ T470] v

[PATCH] remoteproc: virtio: Add synchronize_cbs to remoteproc_virtio

Add synchornize_cbs to rproc_virtio_config_ops and a synchronize_vqs callback to the rproc_ops to ensure vqs' state changes are visible in vring_interrupts when the vq is broken or removed. And when VIRTIO_HARDEN_NOTIFICATION is not set, call rproc_virtio_synchronize_cbs directly in __rproc_virtio
