-    mon: discover mon addrs, names during election state too
-    
-    Currently we only detect new mon addrs and names during the probing phase.
-    For non-trivial clusters, this means we can get into a sticky spot when
-    we discover enough peers to form an quorum, but not all of them, and the
-    undiscovered ones are enough to break the mon ranks and prevent an
-    election.
-    
-    One way to work around this is to continue addr and name discovery during
-    the election.  We should also consider making the ranks less sensitive to
-    the undefined addrs; that is a separate change.

-    mon/Paxos: always refresh after any store_state
-    
-    If we store any new state, we need to refresh the services, even if we
-    are still in the midst of Paxos recovery.  This is because the
-    subscription path will share any committed state even when paxos is
-    still recovering.  This prevents a race like:
-    
-     - we have maps 10..20
-     - we drop out of quorum
-     - we are elected leader, paxos recovery starts
-     - we get one LAST with committed states that trim maps 10..15
-     - we get a subscribe for map 10..20
-       - we crash because 10 is no longer on disk because the PaxosService
-         is out of sync with the on-disk state.

-    osdc/ObjectCacher: do not merge rx buffers
-    
-    We do not try to merge rx buffers currently.  Make that explicit and
-    documented in the code that it is not supported.  (Otherwise the
-    last_read_tid values will get lost and read results won't get applied
-    to the cache properly.)

-    osdc/ObjectCacher: match reads with their original rx buffers
-    
-    Consider a sequence like:
-    
-     1- start read on 100~200
-           100~200 state rx
-     2- truncate to 200
-           100~100 state rx
-     3- start read on 200~200
-           100~100 state rx
-           200~200 state rx
-     4- get 100~200 read result
-    
-    Currently this makes us crash on
-    
-    osdc/ObjectCacher.cc: 738: FAILED assert(bh->length() <= start+(loff_t)length-opos)
-    
-    when processing the second 200~200 bufferhead (it is too big).  The
-    larger issue, though, is that we should not be looking at this data at
-    all; it has been truncated away.
-    
-    Fix this by marking each rx buffer with the read request that is sent to
-    fill it, and only fill it from that read request.  Then the first reply
-    will fill the first 100~100 extend but not touch the other extent; the
-    second read will do that.

-    mon/Paxos: fix another uncommitted value corner case
-    
-    It is possible that we begin the paxos recovery with an uncommitted
-    value for, say, commit 100.  During last/collect we discover 100 has been
-    committed already.  But also, another node provides an uncommitted value
-    for 101 with the same pn.  Currently, we refuse to learn it, because the
-    pn is not strictly > than our current uncommitted pn... even though it is
-    the next last_committed+1 value that we need.
-    
-    There are two possible fixes here:
-    
-     - make this a >= as we can accept newer values from the same pn.
-     - discard our uncommitted value metadata when we commit the value.
-    
-    Let's do both!

-    We were initializing the watch-notify (through the cache

-    early, as we didn't have the control pool name yet. Now

-    enable mds rejoin with active inodes' old parent xattrs
-    
-    When the parent xattrs of active inodes that the mds attempts to open
-    during rejoin lack pool info (struct_v < 5), this field will be filled
-    in with -1, causing the mds to retry fetching a backtrace with a pool
-    number that matches the expected value, which fails and causes the
-    err==-ENOENT branch to be taken and retry pool 1, which succeeds, but
-    with pool -1, and so keeps on bouncing between the two retry cases
-    forever.
-    
-    This patch arranges for the mds to go along with pool -1 instead of
-    insisting that it be refetched, enabling it to complete recovery
-    instead of eating cpu, network bandwidth and metadata osd's resources
-    like there's no tomorrow, in what AFAICT is an infinite and very busy
-    loop.
-    
-    This is not a new problem: I've had it even before upgrading from
-    Cuttlefish to Dumpling, I'd just never managed to track it down, and
-    force-unmounting the filesystem and then restarting the mds was an
-    easier (if inconvenient) work-around, particularly because it always
-    hit when the filesystem was under active, heavy-ish use (or there
-    wouldn't be much reason for caps recovery ;-)
-    
-    There are two issues not addressed in this patch, however.  One is
-    that nothing seems to proactively update the parent xattr when it is
-    found to be outdated, so it remains out of date forever.  Not even
-    renaming top-level directories causes the xattrs to be recursively
-    rewritten.  AFAICT that's a bug.
-    
-    The other is that inodes that don't have a parent xattr (created by
-    even older versions of ceph) are reported as non-existing in the mds
-    rejoin message, because the absence of the parent xattr is signaled as
-    a missing inode (?failed to reconnect caps for missing inodes?).  I
-    suppose this may cause more serious recovery problems.
-    
-    I suppose a global pass over the filesystem tree updating parent
-    xattrs that are out-of-date would be desirable, if we find any parent
-    xattrs still lacking current information; it might make sense to
-    activate it as a background thread from the backtrace decoding
-    function, when it finds a parent xattr that's too out-of-date, or as a
-    separate client (ceph-fsck?).

-    mds: remove waiting lock before merging with neighbours
-    
-    CephFS currently deadlocks under CTDB's ping_pong POSIX locking test
-    when run concurrently on multiple nodes.
-    The deadlock is caused by failed removal of a waiting_locks entry when
-    the waiting lock is merged with an existing lock, e.g:
-    
-    Initial MDS state (two clients, same file):
-    held_locks -- start: 0, length: 1, client: 4116, pid: 7899, type: 2
-    	      start: 2, length: 1, client: 4110, pid: 40767, type: 2
-    waiting_locks -- start: 1, length: 1, client: 4116, pid: 7899, type: 2
-    
-    Waiting lock entry 4116@1:1 fires:
-    handle_client_file_setlock: start: 1, length: 1,
-    			    client: 4116, pid: 7899, type: 2
-    
-    MDS state after lock is obtained:
-    held_locks -- start: 0, length: 2, client: 4116, pid: 7899, type: 2
-    	      start: 2, length: 1, client: 4110, pid: 40767, type: 2
-    waiting_locks -- start: 1, length: 1, client: 4116, pid: 7899, type: 2
-    
-    Note that the waiting 4116@1:1 lock entry is merged with the existing
-    4116@0:1 held lock to become a 4116@0:2 held lock. However, the now
-    handled 4116@1:1 waiting_locks entry remains.
-    
-    When handling a lock request, the MDS calls adjust_locks() to merge
-    the new lock with available neighbours. If the new lock is merged,
-    then the waiting_locks entry is not located in the subsequent
-    remove_waiting() call because adjust_locks changed the new lock to
-    include the old locks.
-    This fix ensures that the waiting_locks entry is removed prior to
-    modification during merge.
