    Note that this commit is actually bisecting the changes from
    Loic Dachary that touch ceph-disk only (ad515bf). As that changeset
    also touches other files it causes conflicts that are not resolvable
    for backporting it to dumpling.

    ceph-disk: make initial journal files 0 bytes
    
    The ceph-osd will resize journal files up and properly fallocate() them
    so that the blocks are preallocated and (hopefully) contiguous.  We
    don't need to do it here too, and getting fallocate() to work from
    python is a pain in the butt.

    ceph-disk: run the right executables from udev
    
    When run by the udev rules, PATH is not defined. Thus,
    ceph-disk-activate relies on its which() function to locate the
    correct executable.  The which() function used os.defpath if none was
    set, and this worked for anything using it.
    
    ad6b4b4b08b6ef7ae8086f2be3a9ef521adaa88c added a new default value to
    PATH, so only /usr/bin was checked by callers that did not use
    which(). This resulted in the mount command not being found when
    ceph-disk-activate was run by udev, and thus osds failing to start
    after being prepared by ceph-deploy.
    
    Make ceph-disk consistently use the existing helpers (command() and
    command_check_call()) that use which(), so lack of PATH does not
    matter. Simplify _check_output() to use command(),
    another wrapper around subprocess.Popen.

    ceph-disk: which() uses PATH first
    
    Instead of relying on a hardcoded set of if paths. Although this has the
    potential of changing the location of the binary being used by ceph-disk
    on an existing installation, it is currently only used for sgdisk. It
    could be disruptive for someone using a modified version of sgdisk but
    the odds of this happening are very low.

    ceph-disk: add --prepend-to-path to control execution
    
    /usr/bin is hardcoded in front of some ceph programs which makes it
    impossible to control where they are located via the PATH.
    
    The hardcoded path cannot be removed altogether because it will most
    likely lead to unexpected and difficult to diagnose problems for
    existing installations where the PATH finds the program elsewhere.
    
    The --prepend-to-path flag is added and defaults to /usr/bin : it prepends
    to the PATH environment variable. The hardcoded path is removed
    and the PATH will be used: since /usr/bin is searched first, the
    legacy behavior will not change.

    ceph-disk: prepare --data-dir must not override files
    
    ceph-disk does nothing when given a device that is already prepared. If
    given a directory that already contains a successfully prepared OSD, it
    will however override it.
    
    Instead of overriding the files in the osd data directory, return
    immediately if the magic file exists. Make it so the magic file is
    created last to accurately reflect the success of the OSD preparation.

    librbd: remove limit on number of objects in the cache
    
    The number of objects is not a significant indicated of when data
    should be written out for rbd. Use the highest possible value for
    number of objects and just rely on the dirty data limits to trigger
    flushing. When the number of objects is low, and many start being
    flushed before they accumulate many requests, it hurts average request
    size and performance for many concurrent sequential writes.

    ObjectCacher: use uint64_t for target and max values
    
    All the options are uint64_t, but the ObjectCacher was converting them
    to int64_t. There's never any reason for these to be negative, so
    change the type.
    
    Adjust a few conditionals so that they only convert known-positive
    signed values to uint64_t before comparing with the target and max
    values. Leave the actual stats accounting as loff_t for now, since
    bugs in accounting will have bad effects if negative values wrap

    common: admin socket fallback to json-pretty format (dumpling)
    
    Reviewed-by: Sage Weil <sage@inktank.com>

    common: admin socket fallback to json-pretty format
    
    If the format argument to a command sent to the admin socket is not
    among the supported formats ( json, json-pretty, xml, xml-pretty ) the
    new_formatter function will return null and the AdminSocketHook::call
    function must fall back to a sensible default.
    
    The CephContextHook::call and HelpHook::call failed to do that and a
    malformed format argument would cause the mon to crash. A check is added
    to each of them and fallback to json-pretty if the format is not
    recognized.
    
    To further protect AdminSocketHook::call implementations from similar
    problems the format argument is checked immediately after accepting the
    command in AdminSocket::do_accept and replaced with json-pretty if it is
    not known.
    
    A test case is added for both CephContextHook::call and HelpHook::call
    to demonstrate the problem exists and is fixed by the patch.
    
    Three other instances of unsafe calls to new_formatter were found and
    a fallback to json-pretty was added. All other calls have been audited
    and appear to be safe.

    osd: OSDMonitor: ignore pgtemps from removed pool
    
    There's a window in-between receiving an MOSDPGTemp message from an OSD
    and actually handling it that may lead to the pool the pg temps refer to
    no longer existing. This may happen if the MOSDPGTemp message is queued
    pending dispatching due to an on-going proposal (maybe even the pool
    removal).
    
    This patch fixes such behavior in two steps:
    
    1. Check if the pool exists in the osdmap upon preprocessing
     - if pool does not exist in the osdmap, then the pool must have been
       removed prior to handling the message, but after the osd sent it.
     - safe to ignore the pg update
    2. If all pg updates in the message have been ignored, ignore the whole
       message.  Otherwise, let prepare handle the rest.
    
    3. Recheck if pool exists in the osdmap upon prepare
     - We may have ignored this pg back in preprocess, but other pgs in the
       message may have led the message to be passed on to prepare; ignore
       pg update once more.
    4. Check if pool is pending removal and ignore pg update if so.
    
    We delegate checking the pending value to prepare_pgtemp() because in this
    case we should only ignore the update IFF the pending value is in fact
    committed.  Otherwise we should retry the message.  prepare_pgtemp() is
    the appropriate place to do so.

    In the RPM spec file there is a test to deploy the uuid hack udev rules
    for older udev operating systems. This includes CentOS and RHEL, but the
    check currently only is for CentOS, causing RHEL clients to get a bogus
    osd rules file.
    
    Adjust the conditional to apply to RHEL as well as CentOS. (The %{rhel}
    macro is defined in both platforms' redhat-rpm-config package.)

    rgw: convert bucket info if needed
    
    Fixes: #7110
    In dumpling, the bucket info was separated into bucket entry point and
    bucket instance objects. When setting bucket attrs we only ended up
    updating the bucket instance object. However, pre-dumpling buckets still
    keep everything at the entry-point object, so acl changes didn't affect
    anything (because we never updated the entry point). This change just
    converts the bucket info into the new format.

    librbd: call user completion after incrementing perfcounters
    
    The perfcounters (and the ictx) are only valid while the image is
    still open.  If the librbd user gets the callback for its last I/O,
    then closes the image, the ictx and its perfcounters will be
    invalid. If the AioCompletion object is has not run the rest of its
    complete() method yet, it will access these now-invalid addresses,
    possibly leading to a crash.
    
    The AioCompletion object is independent of the ictx and does not
    access it again after incrementing perfcounters, so avoid this race by
    calling the user's callback after this step. The AioCompletion object
    will be cleaned up by the rest of complete_request(), independent of
    the ImageCtx.

    It will be returned via put_op_budget() when they complete.
    If there were many localized reads of missing objects from replicas,

    objecter: resend all writes after osdmap loses the full flag
    
    Now that the osd does not respond if it gets a map with the full flag
    set first, clients need to resend all writes.
    
    Clients talking to old osds are still subject to the race condition,
    so both sides must be upgraded to avoid it.

    osd: drop writes when full instead of returning an error
    
    There's a race between the client and osd with a newly marked full
    osdmap.  If the client gets the new map first, it blocks writes and
    everything works as expected, with no errors from the osd.
    
    If the osd gets the map first, however, it will respond to any writes
    with -ENOSPC. Clients will pass this up the stack, and not retry these
    writes later.  -ENOSPC isn't handled well by all clients. RBD, for
    example, may pass it on to qemu or kernel rbd which will both
    interpret it as EIO.  Filesystems on top of rbd will not behave well
    when they receive EIOs like this, especially if the cluster oscillates
    between full and not full, so some writes succeed.
    
    To fix this, never return ENOSPC from the osd because of a map marked
    full, and rely on the client to retry all writes when the map is no
    longer marked full.
    
    Old clients talking to osds with this fix will hang instead of
    propagating an error, but only if they run into this race
    condition. ceph-fuse and rbd with caching enabled are not affected,
    since the ObjectCacher will retry writes that return errors.

    objecter: set op->paused in recalc_op_target(), resend in not paused
    
    When going through scan_requests() in handle_osd_map() we need to make
    sure that if an op should not be paused anymore then set it on the op
    itself, and return NEED_RESEND. Otherwise we're going to miss reset of
    the full flag.
    Also in handle_osd_map(), make sure that op shouldn't be paused before
    sending it. There's a lot of cleanup around that area that we should
    probably be doing, make the code much more tight.

    objecter: don't resend paused ops
    
    Paused ops are meant to block on the client side until a new map that
    unpauses them is recieved. If we send paused writes when the FULL flag
    is set, we'll get -ENOSPC from the osds, which is not what Objecter
    users expect. This may cause rbd without caching to produce an I/O
    error instead of waiting for the cluster to have capacity.
