    osd: fix race in do_recovery()
    
    Verify that the PG is still RECOVERING or BACKFILL when we take the pg
    lock in the recovery thread.  This prevents a crash from an invalid
    state machine event when the recovery queue races with a PG state change
    (e.g., due to peering).

    ObjectCacher: fix off-by-one error in split
    
    This error left a completion that should have been attached
    to the right BufferHead on the left BufferHead, which would
    result in the completion never being called unless the buffers
    were merged before it's original read completed. This would cause
    a hang in any higher level waiting for a read to complete.
    
    The existing loop went backwards (using a forward iterator),
    but stopped when the iterator reached the beginning of the map,
    or when a waiter belonged to the left BufferHead.
    
    If the first list of waiters should have been moved to the right
    BufferHead, it was skipped because at that point the iterator
    was at the beginning of the map, which was the main condition
    of the loop.
    
    Restructure the waiters-moving loop to go forward in the map instead,
    so it's harder to make an off-by-one error.

    os/FileStore: fix non-btrfs op_seq commit order
    
    The op_seq file is the starting point for journal replay.  For stable btrfs
    commit mode, which is using a snapshot as a reference, we should write this
    file before we take the snap.  We normally ignore current/ contents anyway.
    
    On non-btrfs file systems, however, we should only write this file *after*
    we do a full sync, and we should then fsync(2) it before we continue
    (and potentially trim anything from the journal).
    
    This fixes a serious bug that could cause data loss and corruption after
    a power loss event.  For a 'kill -9' or crash, however, there was little
    risk, since the writes were still captured by the host's cache.

    log: broadcast cond signals
    
    We were using a single cond, and only signalling one waiter.  That means
    that if the flusher and several logging threads are waiting, and we hit
    a limit, we the logger could signal another logger instead of the flusher,
    and we could deadlock.
    
    Similarly, if the flusher empties the queue, it might signal only a single
    logger, and that logger could re-signal the flusher, and the other logger
    could wait forever.
    
    Intead, break the single cond into two: one for loggers, and one for the
    flusher.  Always signal the (one) flusher, and always broadcast to all
    loggers.

    When running "service ceph status -a", a version number was never
    returned for remote hosts, only for the local.  This was because
    the command to query the version number didn't use the do_cmd
    function, which is responsible for running the command over SSH
    when needed.

    We need to signal the cond in the same interval where we hold the lock
    *and* modify the queue.  Otherwise, we can have a race like:
    
     queue has 1 item, max is 1.
     A: enter submit_entry, signal cond, wait on condition
     B: enter submit_entry, signal cond, wait on condition
     C: flush wakes up, flushes 1 previous item
     A: retakes lock, enqueues something, exits
     B: retakes lock, condition fails, waits
      -> C is never woken up as there are 2 items waiting

    mds: re-try_set_loner() after doing evals in eval(CInode*, int mask)
    
    Consider a case where current loner is A and wanted loner is B.
    At the top of the function we try to set the loner, but that may fail
    because we haven't processed the gathered caps yet for the previous
    loner.  In the body we do that and potentially drop the old loner, but we
    do not try_set_loner() again on the desired loner.
    
    Try after our drop.  If it succeeds, loop through the eval's one more time
    so that we can issue caps approriately.
    
    This fixes a hang induced by a simple loop like:
    
     while true ; do echo asdf >> mnt.a/foo ; tail mnt.b/foo ; done &
     while true ; do ls mnt.a mnt.b ; done
    
    (The second loop may not be necessary.)

    CompatSet: users pass bit indices rather than masks
    
    CompatSet users number the Feature objects rather than
    providing masks.  Thus, we should do
    
    mask |= (1 << f.id) rather than mask |= f.id.
    
    In order to detect old, broken encodings, the lowest
    bit will be set in memory but not set in the encoding.
    We can reconstruct the correct mask from the names map.
    
    This bug can cause an incompat bit to not be detected
    since 1|2 == 1|2|3.
    
    fixes: #2748

    We were either going to MIX or SYNC depending on whether non-loners wanted

    choosing loner vs not longer is based on anything other that just rd|wr
    wanted.

    ceph-disk-prepare, debian/control: Support external journals.
    
    Previously, ceph-disk-* would only let you use a journal that was a
    file inside the OSD data directory. With this, you can do:
    
      ceph-disk-prepare /dev/sdb /dev/sdb
    
    to put the journal as a second partition on the same disk as the OSD
    data (might save some file system overhead), or, more interestingly:
    
      ceph-disk-prepare /dev/sdb /dev/sdc
    
    which makes it create a new partition on /dev/sdc to use as the
    journal. Size of the partition is decided by $osd_journal_size.
    /dev/sdc must be a GPT-format disk. Multiple OSDs may share the same
    journal disk (using separate partitions); this way, a single fast SSD
    can serve as journal for multiple spinning disks.
    
    The second use case currently requires parted, so a Recommends: for
    parted has been added to Debian packaging.

    Ext4 as a default is a bad choice, as we don't perform enough QA with

    ceph-disk-prepare: Avoid triggering activate before prepare is done.
    
    Earlier testing never saw this, but now a mount of a disk triggers a
    udev blockdev-added event, causing ceph-disk-activate to run even
    before ceph-disk-prepare has had a chance to write the files and
    unmount the disk.
    
    Avoid this by using a temporary partition type uuid ("ceph 2 be"), and
    only setting it to the permanent ("ceph osd"). The hotplug event won't
    match the type uuid, and thus won't trigger ceph-disk-activate.

    Either use ceph.conf variable osd_fs_type or command line option

    Default is still ext4, as currently nothing guarantees xfsprogs
    or btrfs-tools are installed.
    
    Currently both btrfs and xfs seems to trigger a disk hotplug event at
    mount time, thus triggering a useless and unwanted ceph-disk-activate
    run. This will be worked around in a later commit.
    
    Currently mkfs and mount options cannot be configured.
