The 'pool=default' in the default crush maps is confusing wrt rados pools.
'root' makes more sense given that we are talking about hierarchies/trees.

If the queue refcount is the last one for the pg, the pg->put()
in the loop will destroy the pg while the lock is still held
leading to #3071. Thus, grab refcount in case we need to drop
it.

The user log entry contains the request id, which will be used
by replay ops to put themselves in the correct place in the
waiting_for_commit/ack maps. Thus, the repop needs to be tagged
with the same version as the log entry with the request id.
Thus, the request id bearing log entry should be the last in
the log entry vector.
This should fix#3072, wherein a replay which should wait on
the repop tagged as version '36 will instead wait on '35.

want_acting is filled in during recovery completion in
order to move the newly backfilled osd into its correct
place. In this case, however, want_acting must contain
only members of acting and up. Thus, we can be sure that
if any of them go down, we would restart peering anyway.
Thus, we need not transition to WaitActingChange, which
does not reflect that we continue to serve client operations
in the interim.

When we get a pool_op_reply, we find out which osdmap we need to wait for.
The wait_for_new_map() code was feeding that epoch into
maybe_request_map(), which was feeding it to the monitor with the subscribe
request. However, that epoch is the *start* epoch, not what we want. Fix
this code to always subscribe to what we have (+1), and ensure we keep
asking for more until we catch up to what we know we should eventually
get.

Do not special case failure during connect. In particular, we may be
reconnecting and experience a second fault, and wipe out our session
(e.g., between the fs client and the mds) and destroy important session
state.
This logic dates back to the original patch in '08 when the standby
state was introduced.

Uses one index object and many sub objects to store key-value pairs. The pairs
are stored in the omaps of librados objects. The index contains keys
corresponding to the highest key in an object, and values that contain the
name of the object where the key range is stored. The tree guarantees that
the number of pairs in an object will be > k and < 2k for a user-specified k.
KvStoreBench contains benchmarking tests.

Uses a fixed access/secret key for easier testing. Starts a standalone
apache2 process with basic config (based on the teuthology one).
