Merge tag 'xfs-for-linus-3.17-rc1' of git://oss.sgi.com/xfs/xfs

Pull xfs update from Dave Chinner:
 "This update contains:
   - conversion of the XFS core to pass negative error numbers
   - restructing of core XFS code that is shared with userspace to
     fs/xfs/libxfs
   - introduction of sysfs interface for XFS
   - bulkstat refactoring
   - demand driven speculative preallocation removal
   - XFS now always requires 64 bit sectors to be configured
   - metadata verifier changes to ensure CRCs are calculated during log
     recovery
   - various minor code cleanups
   - miscellaneous bug fixes

  The diffstat is kind of noisy because of the restructuring of the code
  to make kernel/userspace code sharing simpler, along with the XFS wide
  change to use the standard negative error return convention (at last!)"
