    then calls the interrupt callback. libfuse need to lock the same mutex
    when unregistering interrupt callback. We unregister interrupt callback
    while client_lock is locked, so we can't acquiring the client_lock in

    crush: improve constness of CrushWrapper methods
    
    A number of CrushWrapper get methods or predicates were not const
    because they need to maintain transparently the rmaps. Make the rmaps
    mutable and update the constness of the methods to match what the caller
    would expect.

    Change CrushWrapper::crush to private
    
    Currently in CrushWrapper, the member "struct crush_map *crush"  is a public member,
    so people can break the encapsulation and manipulate directly to the crush structure.
    
    This is not a good practice for encapsulation and will lead to inconsistent if code
    mix use the CrushWrapper API and crush C API.A simple example could be:
    1.some code use crush_add_rule(C-API) to add a rule, which will not set the have_rmap flag to false in CrushWrapper
    2.another code using CrushWrapper trying to look up the newly added rule by name will get a -ENOENT.
    
    This patch move CrushWrapper::crush to private, together with three reverse map(type_rmap, name_rmap, rule_name_rmap)
    and also change codes accessing the CrushWrapper::crush to make it compile.

    crush: set straw_calc_version=1 for default+optimal; do not touch for presets
    
    When using the presets for compatibility (i.e., based on version), do not
    touch the straw behavior, as it does not affect mapping or compatibility.
    However, make a point of setting it by default and for optimal.
    
    For most users, this means that they will not see any change unless they
    explicitly enable the new behavior, or switch to default or optimal
    tunables.  The idea is that if they touched it, they shouldn't be
    too surprised by the subsequent data movement.

    crush: fix crush_calc_straw() scalers when there are duplicate weights
    
    The straw bucket was originally tested with uniform weights and with a
    few more complicated patterns, like a stair step (1,2,3,4,5,6,7,8,9).  And
    it worked!
    
    However, it does not behave with a pattern like
     1, 2, 2, 3, 3, 4, 4
    
    Strangely, it does behave with
     1, 1, 2, 2, 3, 3, 4, 4
    
    and more usefully it does behave with
     1, 2, 2.001, 3, 3.001, 4, 4.001
    
    That is, the logic that explicitly copes with weights that are duplicates
    is broken.
    
    The fix is to simply remove the special handling for duplicate weights --
    it isn't necessary and doesn't work correctly anyway.
    
    Add a test that compares the mapping result of  [1, 2, 2, 3, 3, ...] with
    [1, 2, 2.001, 3, 3.001, ...] and verifies that the difference is small.
    With the fix, we get .00012, whereas the original implementation gets
    .015.
    
    Note that this changes the straw bucket scalar *precalculated* values that
    are encoded with the map, and only when the admin opts into the new behavior.

    crush: fix distortion of straw scalers by 0-weight items
    
    The presence of a 0-weight item in a straw bucket should have no effect
    on the placement of other items.  Add a test validating that and fix
    crush_calc_straw() to fix the distortion.
    
    Note that this effects the *precalculation* of the straw bucket inputs and
    does not effect the actually mapping process given a compiled or encoded
    CRUSH map, and only when straw_calc_version == 1 (i.e., the admin opted in
    to the new behavior).

    crush: fix incorrect use of adjust_item_weight method
    
    adjust_item_weight method will adjust all buckets which the item
    inside. If the osd.0 in host=fake01 and host=fake02, we execute
    "ceph osd crush osd.0 10 host=fake01", it not only will adjust fake01's
    weight, but also will adjust fake02's weight.

    _remove_item_under, update_item, insert_item, detach_bucket methods.

    crush: recalculate straw scalers during a reweight
    
    The crushtool --reweight function triggers a fresh calculation of bucket
    weights so that they are always the sum of the item weights.  In the
    straw bucket case, the weights were updated but the corresponding straw
    scalers were not being recalculated.  The result is that there was not
    effect on placement in adjusted buckets until the next time a bucket item's
    weight was adjusted.

    init-radosgw.sysv: set ulimit -n before starting daemon
    
    If we do the ulimit inside the daemon command we will have already

    rgw: use s->bucket_attrs instead of trying to read obj attrs
    
    Fixes: #10307
    Backport: firefly, giant
    
    This is needed, since we can't really read the bucket attrs by trying to
    read the bucket entry point attrs. We already have the bucket attrs
    anyway, use these.

    rgw: remove swift user manifest (DLO) hash calculation
    
    Fixes: #9973
    Backport: firefly, giant
    
    Previously we were iterating through the parts, creating hash of the
    parts etags (as S3 does for multipart uploads). However, swift just
    calculates the etag for the empty manifest object.

    fix can not disable max_size quota
    
    Currently if we enable quota and set max_size = -1, it doesn’t
    mean max_size is unlimited as expected. Instead, it means object
    with any size is not allowed to upload because of “QuotaExceeded”.
    The root cause is the function rgw_rounded_kb which convert max_size
    to max_size_kb returns 0 for -1 because it takes an unsigned int
    but we pass an int to it. A simple fix is check max_size before
    it’s rounded to max_size_kb.
    
    Test case:
    1 enable and set quota:
    radosgw-admin quota enable --uid={user_id} --quota-scope=user
    radosgw-admin quota set --quota-scope=user --uid={user_id}\
     --max-objects=100 --max-size=-1
    2 upload any object with non-zero length
    it will return 403 with “QuotaExceeded” and return 200 if you apply the fix.

    rgw: rados->set_attrs() updates bucket index
    
    Fixes: #5595
    Backport: dumpling, firefly
    We need to update the bucket index when updating object attrs, otherwise
    we're missing meta changes that need to be registered. It also
    solves issue of bucket index not knowing about object acl changes,
    although this one still requires some more work.

    rgw-admin: create subuser if needed when creating user
    
    Fixes: #10103
    Backport: firefly, giant
    This turned up after fixing #9973. Earlier we also didn't create the
    subuser in this case, but we didn't really read the subuser info when it
    was authenticating. Now we do that as required, so we end up failing the
    authentication. This only applies to cases where a subuser was created
    using 'user create', and not the 'subuser create' command.
