Tiwei seems to be right - include/uapi/linux/vhost.h and
include/uapi/linux/vhost_types.h are both existing files. vhost uapi
extensions included here are very modest. They
just add virtio spec things that vhost was missing.
Are you looking at a very old linux tree maybe?
vhost_types.h appeared around 4.20.
