inflight

size_t srn_reactor_io_channel_t::inflight

Operations submitted on this channel and not yet consumed.

Touched only by the channel's owning worker os thread (the submit path bumps it, the consume path drops it), so it needs no atomics. Admission control caps it at the ring capacity, which is what makes a full SQ or CQ impossible.
