we keep the state stored in an atomic integer to protect against bad
usage.

the ovni model, as libovni will already pre-populate it for the user.

The ring buffer pointers are no longer valid as we may have displaced
events around. The pointers of the affected region are reconstructed by
reading the events again, following their size.
