Pull xfs updates from Dave Chinner:
 "This is a big update with lots of new code. The summary below them
  all, so I'll just touch on teh higlights. The two main new features
  are Large Extent Counts and Logged Attribute Replay - these are two
  new foundational features that we are building more complex future
  features on top of.

  For upcoming functionality, we need to be able to store hundreds of
  millions of xattrs per inode. The Large Extent Count feature removes
  the limits that prevent this scale of xattr storage, and while we were
  modifying the on disk extent count format we also increased the number
  of data extents we support per inode from 2^32 to 2^47.

  We also need to be able to modify xattrs as part of larger atomic
  transactions rather than as standalone transactions. The Logged
  Attribute Replay feature introduces the infrastructure that allows us
  to use intents to record the attribute modifications in the journal
  before we start them, hence allowing other atomic transactions to log
  attribute modification intents and then defer the actual modification
  to later. If we then crash, log recovery then guarantees that the
  attribute is replayed in the context of the atomic transaction that
  logged the intent.

  A significant chunk of the commits in this merge are for the base
  attribute replay functionality along with fixes, improvements and
  cleanups related to this new functioanlity. Allison deserves a big
  round of thanks for her ongoing work to get this functionality into
  XFS.

  There are also many other smaller changes and improvements, so overall
  this is one of the bigger XFS merge requests in some time.

  I will be following up next week with another smaller pull request -
  we already have another round of fixes and improvements to the logged
  attribute replay functionality just about ready to go. They'll soak
  and test over the next week, and I'll send a pull request for them
  near the end of the merge window.

  Summary:

   - support for printk message indexing.

   - large extent counts to provide support for up to 2^47 data extents
     and 2^32 attribute extents, allowing us to scale beyond 4 billion
     data extents to billions of xattrs per inode.

   - conversion of various flags fields to be consistently declared as
     unsigned bit fields.

   - improvements to realtime extent accounting and converts them to
     per-cpu counters to match all the other block and inode accounting.

   - reworks core log formatting code to reduce iterations, have a
     shorter, cleaner fast path and generally be easier to understand
     and maintain.

   - improvements to rmap btree searches that reduce overhead by up to
     30% resulting in xfs_scrub runtime reductions of 15%.

   - improvements to reflink that remove the size limitations in
     remapping operations and greatly reduce the size of transaction
     reservations.

   - reworks the minimum log size calculations to allow us to change
     transaction reservations without changing the minimum supported log
     size.

   - removal of quota warning support as it has never been used on
     Linux.

   - intent whiteouts to allow us to cancel intents that are completed
     entirely in memory rather than having use CPU and disk bandwidth
     formatting and writing them into the journal when it is not
     necessary. This makes rmap, reflink and extent freeing slightly
     more efficient, but provides massive improvements for....

   - Logged Attribute Replay feature support. This is a fundamental
     change to the way we modify attributes, laying the foundation for
     future integration of attribute modifications as part of other
     atomic transactional operations the filesystem performs.

   - Lots of cleanups and fixes for the logged attribute replay
     functionality"
