    mon: MDSMonitor: wait for osdmon to be writable when requesting proposal
    
    Otherwise we may end up requesting the osdmon to propose while it is
    mid-proposal.  We can't simply return EAGAIN to the user either because
    then we would have to expect the user to be able to successfully race
    with the whole cluster in finding a window in which 'mds fs new' command
    would succeed -- which is not a realistic expectation.  Having the
    command to osdmon()->wait_for_writable() guarantees that the command
    will be added to a queue and that we will, eventually, tend to it.

    mon: MDSMonitor: have management_command() returning int instead of bool
    
    We can more easily differentiate between errors we get out of this
    function, which makes the code a bit more versatile and readable.

    Objecter: failed assert(tick_event==NULL) at osdc/Objecter.cc
    
    When the Objecter timer erases the tick_event from its events queue and
    calls tick() to dispatch it, if the Objecter::rwlock is held by shutdown(),
    it waits there to get the rwlock. However, inside the shutdown function,
    it checks the tick_event and tries to cancel it. The cancel_event function
    returns false since tick_event is already removed from the events queue. Thus
    tick_event is not set to NULL in shutdown(). Later the tick function return
    ealier and doesn't set tick_event to NULL as well. This leads to the assertion
    failure.
    
    This is a regression introduced by an incorrect conflict resolution when
    d790833 was backported.

    librados: Translate operation flags from C APIs
    
    The operation flags in the public C API are a distinct enum
    and need to be translated to Ceph OSD flags, like as happens in
    the C++ API. It seems like the C enum and the C++ enum consciously
    use the same values, so I reused the C++ translation function.

    Objecter: check the 'initialized' atomic_t safely
    
    shutdown() resets initialized to 0, but we can still receive messages
    after this point, so fix message handlers to skip messages in this
    case instead of asserting.
    
    Also read initialized while holding Objecter::rwlock to avoid races
    where e.g. handle_osd_map() checks initialized -> 1, continues,
    shutdown() is called, sets initialized to 0, then handle_osd_map()
    goes about its business and calls op_submit(), which would fail the
    assert(initialized.read()) check. Similar races existed in other
    message handlers which change Objecter state.
    
    The Objecter is not destroyed until after its Messenger in
    the MDS, OSD, and librados, so this should be safe.

    CrushWrapper: pick a ruleset same as rule_id
    
    Originally in the add_simple_ruleset funtion, the ruleset_id
    is not reused but rule_id is reused. So after some add/remove
    against rules, the newly created rule likely to have
    ruleset!=rule_id.

    that ruleset == rule_id.

    SimpleMessenger: allow RESETSESSION whenever we forget an endpoint
    
    In the past (e229f8451d37913225c49481b2ce2896ca6788a2) we decided to disable
    reset of lossless Pipes, because lossless peers resetting caused trouble and
    they can't forget about each other. But they actually can: if mark_down()
    is called.
    
    I can't figure out how else we could forget about a remote endpoint, so I think
    it's okay if we tell them we reset in order to clean up state. That's desirable
    so that we don't get into strange situations with out-of-whack counters.

    When updating submodules, always checkout even if the HEAD is the
    desired commit hash (update --force) to avoid the following:
    
        * a directory gmock exists in hammer
        * a submodule gmock replaces the directory gmock in master
        * checkout master + submodule update : gmock/.git is created
        * checkout hammer : the gmock directory still contains the .git from
          master because it did not exist at the time and checkout won't
          remove untracked directories
        * checkout master + submodule update : git rev-parse HEAD is
          at the desired commit although the content of the gmock directory
          is from hammer

    common: do not unlock rwlock on destruction
    
    According to pthread_rwlock_unlock(3p):
    
     Results are undefined if the read-write lock rwlock is not held
     by the calling thread.
    
    and:
    
     https://sourceware.org/bugzilla/show_bug.cgi?id=17561
    
     Calling pthread_rwlock_unlock on an rwlock which is not locked
     is undefined.
    
    calling pthread_rwlock_unlock on RWLock destruction could cause
    an unknown behavior for two reasons:
    
    - the lock is acquired by another thread (undefined)
    - the lock is not acquired (undefined)
    
    Moreover since glibc-2.20 calling pthread_rwlock_unlock on a
    rwlock that is not locked results in a SIGILL that kills the
    application.
    
    This patch removes the pthread_rwlock_unlock call on destruction
    and replaces it with an assertion to check that the RWLock is
    not in use.
    
    Any code that relied on the implicit release is now going to
    break the assertion, e.g.:
    
     {
       RWLock l;
       l.get(for_write);
     } // implicit release, wrong.

    randomly choosing a value between 0 and the max.

    mon: MonCap: take EntityName instead when expanding profiles
    
    entity_name_t is tightly coupled to the messenger, while EntityName is
    tied to auth.  When expanding profiles we want to tie the profile
    expansion to the entity that was authenticated.  Otherwise we may incur
    in weird behavior such as having caps validation failing because a given
    client messenger inst does not match the auth entity it used.
    
    e.g., running
    
    ceph --name osd.0 config-key exists foo daemon-private/osd.X/foo
    
    has entity_name_t 'client.12345' and EntityName 'osd.0'.  Using
    entity_name_t during profile expansion would not allow the client access
    to daemon-private/osd.X/foo (client.12345 != osd.X).

    rados.py: keep reference to python callbacks
    
    If we don't keep a reference to these, the librados aio calls will
    segfault since the python-level callbacks will have been garbage
    collected. Passing them to aio_create_completion() does not take a
    reference to them. Keep a reference in the python Completion object
    associated with the request, since they need the same lifetime.
    
    This fixes a regression from 60b019f69aa0e39d276c669698c92fc890599f50.

    osd: requeue blocked op before flush it was blocked on
    
    If we have request A (say, cache-flush) that blocks things, and then
    request B that gets blocked on it, and we have an interval change, then we
    need to requeue B first, then A, so that the resulting queue will keep
    A before B and preserve the order.

    crush: set_choose_tries = 100 for erasure code rulesets
    
    It is common for people to try to map 9 OSDs out of a 9 OSDs total ceph
    cluster. The default tries (50) will frequently lead to bad mappings for
    this use case. Changing it to 100 makes no significant CPU performance
    difference, as tested manually by running crushtool on one million
    mappings.
