Merge git://oss.sgi.com:8090/oss/git/xfs-2.6

* git://oss.sgi.com:8090/oss/git/xfs-2.6:
  [XFS] Cleanup in XFS after recent get_block_t interface tweaks.
  [XFS] Remove unused/obsoleted function: xfs_bmap_do_search_extents()
  [XFS] A change to inode chunk allocation to try allocating the new chunk
  Fixes a regression from the recent "remove ->get_blocks() support"
  [XFS] Fix compiler warning and small code inconsistencies in compat
  [XFS] We really suck at spulling.  Thanks to Chris Pascoe for fixing all
