Pull moar xfs updates from Darrick Wong:
 "This contains a fix for a deadlock in the allocator. It continues the
  slow march towards being able to offline AGs, and it refactors the
  interface to the xfs allocator to be less indirection happy.

  Summary:

   - Fix a deadlock in the free space allocator due to the AG-walking
     algorithm forgetting to follow AG-order locking rules

   - Make the inode allocator prefer existing free inodes instead of
     failing to allocate new inode chunks when free space is low

   - Set minleft correctly when setting allocator parameters for bmap
     changes

   - Fix uninitialized variable access in the getfsmap code

   - Make a distinction between active and passive per-AG structure
     references. For now, active references are taken to perform some
     work in an AG on behalf of a high level operation; passive
     references are used by lower level code to finish operations
     started by other threads. Eventually this will become part of
     online shrink

   - Split out all the different allocator strategies into separate
     functions to move us away from design antipattern of filling out a
     huge structure for various differentish things and issuing a single
     function multiplexing call

   - Various cleanups in the filestreams allocator code, which we might
     very well want to deprecate instead of continuing

   - Fix a bug with the agi rotor code that was introduced earlier in
     this series"
