We don't rely on lockless guarantees, but it seems cleaner than inverting __ptr_ring_peek. Signed-off-by: Michael S.

struct vring (in the uapi directory) and supporting APIs are kept around to avoid breaking old userspace builds. It's not actually part of the UAPI - it was kept in the UAPI header by mistake, and using it in kernel isn't necessary and prevents us from making changes safely. In particular, the APIs actually assume the legacy layout. Add struct vring_s (identical ATM) and supporting legacy
