    When completing the part upload we need to flush any data that we
    aggregated and didn't flush yet. With earlier code didn't have to deal
    with it as for multipart upload we didn't have any pending data.
    What we do now is we call the regular atomic data completion
    function that takes care of it.

    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.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!

    rgw: change cache / watch-notify init sequence
    
    Fixes: #6046
    We were initializing the watch-notify (through the cache
    init) before reading the zone info which was much too
    early, as we didn't have the control pool name yet. Now
    simplifying init/cleanup a bit, cache doesn't call watch/notify
    init and cleanup directly, but rather states its need
    through a virtual callback.

    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.
