  "message": "virtio: console: Add reference counting for port struct\n\nWhen a port got hot-unplugged, when a port was open, any file operation\nafter the unplugging resulted in a crash. This is fixed by ref-counting\nthe port structure, and releasing it only when the file is closed.\n\nThis splits the unplug operation in two parts: first marks the port\nas unavailable, removes all the buffers in the vqs and removes the port\nfrom the per-device list of ports. The second stage, invoked when all\nreferences drop to zero, releases the chardev and frees all other memory.\n\nSigned-off-by: Amit Shah \u003camit.shah@redhat.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n",
