* This is much more general than is actually required by PrimaryLogPG.
* Only 4 flavors of multi-object transactions actually happen:
* 1) rename temp -> object for copyfrom
* 2) clone head -> clone, modify head for make_writeable on normal head write
* 3) clone clone -> head for rollback
* 4) 2 + 3
*
* We can bypass the below logic for single object transactions trivially
* (including case 1 above since temp doesn't show up again).
* For 2-3, we could add something ad-hoc to ensure that they happen in the
* right order, but it actually seems easier to just do the graph construction.

* In general, we need to send a delete and a copyfrom.
* Consider snapc 10:[10, 9, 8, 4, 3, 2]:[10(10, 9), 4(4,3,2)]
* where 4 is marked as clean. To flush 10, we have to:
* 1) delete 4:[4,3,2] -- Logically, the object does not exist after 4
* 2) copyfrom 8:[8,4,3,2] -- flush object after snap 8
*
* There is a complicating case. Supposed there had been a clone 7
* for snaps [7, 6] which has been trimmed since they no longer exist.
* In the base pool, we'd have 5:[4,3,2]:[4(4,3,2)]+head. When we submit
* the delete, the snap will be promoted to 5, and the head will become
* a whiteout. When the copy-from goes through, we'll end up with
* 8:[8,4,3,2]:[4(4,3,2)]+head.
*
* Another complication is the case where there is an interval change
* after doing the delete and the flush but before marking the object
* clean. We'll happily delete head and then recreate it at the same
* sequence number, which works out ok.

*
* The 2) mapping is arranged such that all objects in a particular
* snap will sort together, and so that all objects in a pg for a
* particular snap will group under up to 8 prefixes.

* 2) List a set of subsets of the OSDs such that contacting at least
* one from each subset guarantees we speak to at least one witness
* of any completed write.
*
* Crucially, 2) does not require keeping *all* past intervals. Certainly,
* we don't need to keep any where maybe_went_rw would be false. We also
* needn't keep two intervals where the actingset in one is a subset
* of the other (only need to keep the smaller of the two sets). In order
* to accurately trim the set of intervals as last_epoch_started changes
* without rebuilding the set from scratch, we'll retain the larger set
* if it in an older interval.

* Reserving/freeing scrub resources at the replicas.
*
* When constructed - sends reservation requests to the acting_set.
* A rejection triggers a "couldn't acquire the replicas' scrub resources"
* event. All previous requests, whether already granted or not, are explicitly
* released.
*
* Timeouts:
*
* Slow-Secondary Warning:
* Once at least half of the replicas have accepted the reservation, we start
* reporting any secondary that takes too long (more than <conf> milliseconds
* after the previous response received) to respond to the reservation request.
* (Why? because we have encountered real-life situations where a specific OSD
* was systematically very slow (e.g. 5 seconds) to respond to the reservation
* requests, slowing the scrub process to a crawl).
*
* Reservation Timeout:
* We limit the total time we wait for the replicas to respond to the
* reservation request. If we don't get all the responses (either Grant or
* Reject) within <conf> milliseconds, we give up and release all the
* reservations we have acquired so far.
* (Why? because we have encountered instances where a reservation request was
* lost - either due to a bug or due to a network issue.)
*
* A note re performance: I've measured a few container alternatives for
* m_reserved_peers, with its specific usage pattern. Std::set is extremely
* slow, as expected. flat_set is only slightly better. Surprisingly -
* std::vector (with no sorting) is better than boost::small_vec. And for
* std::vector: no need to pre-reserve.

/* Journaler
*
* This class stripes a serial log over objects on the store. Four
* logical pointers:
*
* write_pos - where we're writing new entries
* unused_field - where we're reading old entires
* expire_pos - what is deemed "old" by user
* trimmed_pos - where we're expiring old items
*
* trimmed_pos <= expire_pos <= unused_field <= write_pos.
*
* Often, unused_field <= write_pos (as with MDS log). During
* recovery, write_pos is undefined until the end of the log is
* discovered.
*
* A "head" struct at the beginning of the log is used to store
* metadata at regular intervals. The basic invariants include:
*
* head.unused_field <= unused_field -- the head may "lag", since
* it's updated lazily.
* head.write_pos <= write_pos
* head.expire_pos <= expire_pos
* head.trimmed_pos <= trimmed_pos
*
* More significantly,
*
* head.expire_pos >= trimmed_pos -- this ensures we can find the
* "beginning" of the log as last
* recorded, before it is trimmed.
* trimming will block until a
* sufficiently current expire_pos
* is committed.
*
* To recover log state, we simply start at the last write_pos in the
* head, and probe the object sequence sizes until we read the end.
*
* Head struct is stored in the first object. Actual journal starts
* after layout.period() bytes.
