+    rgw: bucket index ops on system buckets shouldn't do anything
+    
+    Fixes: #4508
+    Backport: bobtail
+    On certain bucket index operations we didn't check whether
+    the bucket was a system bucket, which caused the operations
+    to fail. This triggered an error message on bucket removal
+    operations.

+    os/FileJournal: fix aio self-throttling deadlock
+    
+    This block of code tries to limit the number of aios in flight by waiting
+    for the amount of data to be written to grow relative to a function of the
+    number of aios.  Strictly speaking, the condition we are waiting for is a
+    function of both aio_num and the write queue, but we are only woken by
+    changes in aio_num, and were (in rare cases) waiting when aio_num == 0 and
+    there was no possibility of being woken.
+    
+    Fix this by verifying that aio_num > 0, and restructuring the loop to
+    recheck that condition on each wakeup.

+    client: use 4MB f_bsize and f_frsize for statfs
+    
+    Old stat(1) reports:
+    
+      Block size: 1048576    Fundamental block size: 1048576
+    
+    and the df(1) arithmetic works out.  New stat(1) reports:
+    
+      Block size: 1048576    Fundamental block size: 4096
+    
+    which is what we are shoving into statvfs, but we have the b_size and
+    fr_size arithmetic swapped.  However, doing the *correct* reporting would
+    then break the old stat by making both sizes appear to be 4KB (or
+    whatever).
+    
+    Sidestep the issue by making *both* values 4MB.. which is both large enough
+    to report large FS sizes, and also the default stripe size and thus a
+    "reasonable" value to report for a block size.
+    
+    Perhaps in the future, when we no longer care about old userland, we can
+    report the page size for f_bsize, which is probably the "most correct"
+    thing to do.
+    
+    Fixes: #3794.  See also #3793.

+    osd: update snap collections for sub_op_modify log records conditionaly
+    
+    The only remaining caller is sub_op_modify().  If we do have a non-empty
+    op transaction, we want to do this update, regardless of what we think
+    last_backfill is (our notion may be not completely in sync with the
+    primary).  In particular, our last_backfill may be the same object but
+    a different snapid, but the primary disagrees and is pushing an op
+    transaction through.
+    
+    Instead, update the collections if we have a non-empty transaction.

+    Previously we would only encode the updated snaps vector for CLONE ops.
+    This doesn't work for MODIFY ops generated by the snap trimmer, which
+    may also adjust the clone collections.  It is also possible that other

+    osd: mark down connections from old peers
+    
+    Close out any connection with an old peer.  This avoids a race like:
+    
+    - peer marked down
+    - we get map, mark down the con
+    - they reconnect and try to send us some stuff
+    - we share our map to tell them they are old and dead, but leave the con
+      open
+    ...
+    - peer marks itself up a few times, eventually reuses the same port
+    - sends messages on their fresh con
+    - we discard because of our old con
+    
+    This could cause a tight reconnect loop, but it is better than wrong
+    behavior.
+    
+    Other possible fixes:
+     - make addr nonce truly unique (augment pid in nonce)

+    msgr: drop messages on cons with CLOSED Pipes
+    
+    Back in commit 6339c5d43974f4b495f15d199e01a141e74235f5, we tried to make
+    this deal with a race between a faulting pipe and new messages being
+    queued.  The sequence is
+    
+    - fault starts on pipe
+    - fault drops pipe_lock to unregister the pipe
+    - user (objecter) queues new message on the con
+    - submit_message reopens a Pipe (due to this bug)
+    - the message managed to make it out over the wire
+    - fault finishes faulting, calls ms_reset
+    - user (objecter) closes the con
+    - user (objecter) resends everything
+    
+    It appears as though the previous patch *meant* to drop *m on the floor in
+    this case, which is what this patch does.  And that fixes the crash I am
+    hitting; see #4271.

+    osd: requeue pg waiters at the front of the finished queue
+    
+    We could have a sequence like:
+    
+    - op1
+    - notify
+    - op2
+    
+    in the finished queue.  Op1 gets put on waiting_for_pg, the notify
+    creates the pg and requeues op1 (and the end), op2 is handled, and
+    finally op1 is handled.  That breaks ordering; see #2947.
+    
+    Instead, when we wake up a pg, queue the waiting messages at the front
+    of the dispatch queue.

+    osd: pull requeued requests off one at a time
+    
+    Pull items off the finished queue on at a time.  In certain cases, an
+    event may result in new items betting added to the finished queue that
+    will be put at the *front* instead of the back.  See latest incarnation
+    of #2947.
+    
+    Note that this is a significant changed in behavior in that we can
+    theoretically starve if an event keeps resulting in new events getting
+    generated.  Beware!

+    
+    In certain cases, we may replay the journal and not end up with the
+    dirfrag for mydir open.  This is fine--we just need to open it up and
+    fetch it below.

+    mds: use inode_t::layout for dir layout policy
+    
+    Remove the default_file_layout struct, which was just a ceph_file_layout,
+    and store it in the inode_t.  Rip out all the annoying code that put this
+    on the heap.
+    
+    To aid in this usage, add a clear_layout() function to inode_t.

+    Strip any trailing whitespace from rbd showmapped
+    
+    More recent versions of ceph append a bit of whitespace to the line
+    after the name of the /dev/rbdX device; this causes the monitor check
+    to fail as it can't find the device name due to the whitespace.
+    
+    This fix excludes any characters after the /dev/rbdN match.
