The patches are merged upstream. I don't know of any other bugs like that (crashes, hangs, etc). There is the one we can't reproduce so are not sure if it's the vhost changes. There is the change in behavior type of bug we discussed in that thread: https://lore.kernel.org/all/06369c2c-c363-4def-9ce0-f018a9e10e8d@xxxxxxxxxx/T/#m026f7dd96e064e3a604155e45e7ae9d5c949ae23
