+
+ Each PG slot includes queues for events that are processing and/or waiting
+ for a PG to be materialized in the slot.
+
+ These are the constraints:
+
+ - client ops must remained ordered by client, regardless of std::map epoch
+ - peering messages/events from peers must remain ordered by peer
+ - peering messages and client ops need not be ordered relative to each other
+
+ - some peering events can create a pg (e.g., notify)
+ - the query peering event can proceed when a PG doesn't exist
+
+ Implementation notes:
+
+ - everybody waits for split. If the OSD has the parent PG it will instantiate
+ the PGSlot early and mark it waiting_for_split. Everything will wait until
+ the parent is able to commit the split operation and the child PG's are
+ materialized in the child slots.
+
+ - every event has an epoch property and will wait for the OSDShard to catch
+ up to that epoch. For example, if we get a peering event from a future
+ epoch, the event will wait in the slot until the local OSD has caught up.
+ (We should be judicious in specifying the required epoch [by, e.g., setting
+ it to the same_interval_since epoch] so that we don't wait for epochs that
+ don't affect the given PG.)
+
+ - we maintain two separate wait lists, *waiting* and *waiting_peering*. The
+ OpSchedulerItem has an is_peering() bool to determine which we use. Waiting
+ peering events are queued up by epoch required.
+
+ - when we wake a PG slot (e.g., we finished split, or got a newer osdmap, or
+ materialized the PG), we wake *all* waiting items. (This could be optimized,
+ probably, but we don't bother.) We always requeue peering items ahead of
+ client ops.
+
+ - some peering events are marked !peering_requires_pg (PGQuery). if we do
+ not have a PG these are processed immediately (under the shard lock).
+
+ - we do not have a PG present, we check if the slot maps to the current host.
+ if so, we either queue the item and wait for the PG to materialize, or
+ (if the event is a pg creating event like PGNotify), we materialize the PG.
+
+ - when we advance the osdmap on the OSDShard, we scan pg slots and
+ discard any slots with no pg (and not waiting_for_split) that no
+ longer std::map to the current host.
