Detailed Description

Mutable record of one rmap entry observed during a walk.

Returned by collect_peers under the stripe lock. Carrying the slot_index field lets the caller clear the peer slot from outside the stripe lock, which is required because slot clear re-enters rmap via remove, and re-entering the same stripe lock would deadlock.
