    rocksdb: disable tcmalloc if disabled
    
    the rocksdb/configure.ac does not support --with-tcmalloc before,
    and the updated rocksdb commit has the change for '--with-tcmalloc'

    Commit 221efb0b893adbfd7a19df171cf967fee87afcc7 altered the rST source
    for the ceph-disk man page. In Hammer, we also have to modify the nroff
    sources, because static copies of the generated man pages are stored in
    Git.

    mon/OSDMonitor: improve reweight_by_utilization() logic
    
    By calling reweight_by_utilization() method, we are aiming at an evener result
    of utilization among all osds. To achieve this, we shall decrease weights of
    osds which are currently overloaded, and try to increase weights of osds which
    are currently underloaded when it is possible.
    However, we can't do this all at a time in order to avoid a massive pg migrations
    between osds. Thus we introduce a max_osds limit to smooth the progress.
    
    The problem here is that we have sorted the utilization of all osds in a descending
    manner and we always try to decrease the weights of the most overloaded osds
    since they are most likely to encounter a nearfull/full transition soon, but
    we won't increase the weights from the most underloaded(least utilized by contrast)
    at the same time, which I think is not quite reasonable.
    
    Actually, the best thing would probably be to iterate over teh low and high osds
    in parallel, and do the ones that are furthest from the average first.

    osd: reset session->osdmap if session is not waiting for a map anymore
    
    we should release the osdmap reference once we are done with it,
    otherwise we might need to wait very long to update that reference with
    a newer osdmap ref. this appears to be an OSDMap leak: it is held by an
    quiet OSD::Session forever.
    
    the osdmap is not reset in OSD::session_notify_pg_create(), because its
    only caller is wake_pg_waiters(), which will call
    dispatch_session_waiting() later. and dispatch_session_waiting() will
    check the session->osdmap, and will also reset the osdmap if
    session->waiting_for_pg.empty().

    rgw: Set Access-Control-Allow-Origin to a Asterisk if allowed in a rule
    
    Before this patch the RGW would respond with the Origin send by the client in the request
    if a wildcard/asterisk was specified as a valid Origin.
    
    This patch makes sure we respond with a header like this:
    
      Access-Control-Allow-Origin: *
    
    This way a resource can be used on different Origins by the same browser and that browser
    will use the content as the asterisk.
    
    We also keep in mind that when Authorization is send by the client different rules apply.
    In the case of Authorization we may not respond with an Asterisk, but we do have to
    add the Vary header with 'Origin' as a value to let the browser know that for different
    Origins it has to perform a new request.

    rgw: keep track of written_objs correctly
    
    Fixes: http://tracker.ceph.com/issues/15886
    
    Only add a rados object to the written_objs list if the write
    was successful. Otherwise if the write will be canceled for some
    reason, we'd remove an object that we didn't write to. This was
    a problem in a case where there's multiple writes that went to
    the same part. The second writer should fail the write, since
    we do an exclusive write. However, we added the object's name
    to the written_objs list anyway, which was a real problem when
    the old processor was disposed (as it was clearing the objects).

    osd: remove all stale osdmaps in handle_osd_map()
    
    in a large cluster, there are better chances that the OSD fails to trim
    the cached osdmap in a timely manner. and sometimes, it is just unable
    to keep up with the incoming osdmap if skip_maps, so the osdmap cache
    can keep building up to over 250GB in size. in this change
    
    * publish_superblock() before trimming the osdmaps, so other osdmap
      consumers of OSDService.superblock won't access the osdmaps being
      removed.
    * trim all stale osdmaps in batch of conf->osd_target_transaction_size
      if skip_maps is true. in my test, it happens when the osd only
      receives the osdmap from monitor occasionally because the osd happens
      to be chosen when monitor wants to share a new osdmap with a random
      osd.
    * always use dedicated transaction(s) for trimming osdmaps. so even in
      the normal case where we are able to trim all stale osdmaps in a
      single batch, a separated transaction is used. we can piggy back
      the commits for removing maps, but we keep it this way for simplicity.
    * use std::min() instead MIN() for type safety

    This change is taken from 069d95eaf49cadaa9a8fa1fa186455944a50ec7d
    but I did not want to cherry-pick that patch since the rest of it

    mon/MonClient: fix shutdown race
    
    While we are shutting down, we should drop all subsequent mon
    messages.  Currently it is possible to finish the authentication
    sequence *while* we are shutting down, such that a subsequent
    attempt to authenticate succeeds.
    
    Fix this by resetting cur_con early in the sequence, as this
    makes us drop all incoming messages.

    tests: be more generous with test timeout
    
    When the thrasher is in action together with a validater (lockdep or
    valgrind), a single test may hang for more than 360 seconds. Increase to
    1200: it does not matter if the value is large, only that it prevents
    the test from hanging forever.

    rgw: user quota may not adjust on bucket removal
    
    Description:
    If the user/admin removes a bucket using --force/--purge-objects options with s3cmd/radosgw-admin respectively, the user stats will continue to reflect the deleted objects for quota purposes, and there seems to be no way to reset them. User stats need to be sync'ed prior to bucket removal.
    
    Solution:
    Sync user stats before removing a bucket.

    Backport Change:
    We remove the `tenant` parameter because this feature is not introduced on hammer version.
    The rgw multi-tenant feature is introduced on pr#6784 (https://github.com/ceph/ceph/pull/6784)
    This feature is supported from v10.0.2 and later version.

    rgw: Do not send a Content-Length header on a 304 response
    
    We tell the client that the content has not changed. If we
    send a Content-Length header RFC2616 describes that the client
    MUST use that new value:
    
    "If a cache uses a received 304 response to update a cache entry,
    the cache MUST update the entry to reflect any new field values
    given in the response."
    
    Therefor we should not send a Content-Length header

    Fixed the ceph get mdsmap assertion.
    
        When we want to get mdsmap, we try to get_version()
        and the return value err = 0 means success.
    
        The assert verified r == 0. r would not change in this flow.
        It always meet assert and lead mon failure.
    
        I think this verify should be:
            assert(err == 0)
        It will help to check return value of get_version().
    
    If you have any questions, feel free to let me know.
    Thanks!
