+    mon/OSDMonitor: fix base case for 7fb3804fb workaround
+    
+    After cluster creation, we have no full map stored and first_committed ==
+    1.  In that case, there is no need for a full map, since we can get there
+    from OSDMap() and the incrementals.

+    mon: OSDMonitor: work around a full version bug introduced in 7fb3804fb
+    
+    In 7fb3804fb860dcd0340dd3f7c39eec4315f8e4b6 we moved the full version
+    stashing logic to the encode_trim_extra() function.  However, we forgot
+    to update the osdmap's 'latest_full' key that should always point to
+    the latest osdmap full version.  This eventually degenerated in a missing
+    full version after a trim.  This patch works around this bug by looking
+    for the latest available full osdmap version in the store and updating
+    'latest_full' to its proper value.
+    
+    Related-to: #5704

+
+    mon: OSDMonitor: update the osdmap's latest_full with the new full version
+    
+    We used to do this on encode_full(), but since [1] we no longer rely on
+    PaxosService to manage the full maps for us.  And we forgot to write down
+    the latest_full version to the store, leaving it in a truly outdated state.

+    mon: decline to scrub when paxos is not active
+    
+    In f1ce8d7c955a2443111bf7d9e16b4c563d445712 we close a race between scrub
+    and paxos commit completion on the leader.  The fix is nontrivial to
+    backport and probably not worthwhile; just avoid scrubbing at that time
+    for now.
+    
+    Note that the actual fix for this is in commit
+    f1ce8d7c955a2443111bf7d9e16b4c563d445712.
