Merge tag 'xfs-for-linus-v3.13-rc1' of git://oss.sgi.com/xfs/xfs

Pull xfs update from Ben Myers:
 "For 3.13-rc1 we have an eclectic assortment of bugfixes, cleanups, and
  refactoring.  Bugfixes that stand out are the fix for the AGF/AGI
  deadlock, incore extent list fixes, verifier fixes for v4 superblocks
  and growfs, and memory leaks.  There are some asserts, warnings, and
  strings that were cleaned up.  There was further rearrangement of code
  to make libxfs and the kernel sync up more easily, differences between
  v2 and v3 directory code were abstracted using an ops vector,
  xfs_inactive was reworked, and the preallocation/hole punching code
  was refactored.

   - simplify kmem_zone_zalloc
   - add traces for AGF/AGI read ops
   - add additional AIL traces
   - fix xfs_remove AGF vs AGI deadlock
   - fix the extent count of new incore extent page in the indirection
     array
   - don't fail bad secondary superblocks verification on v4 filesystems
     due to unzeroed bits after v4 fields
   - fix possible NULL dereference in xlog_verify_iclog
   - remove redundant assert in xfs_dir2_leafn_split
   - prevent stack overflows from page cache allocation
   - fix some sparse warnings
   - fix directory block format verifier to check the leaf entry count
   - abstract the differences in dir2/dir3 via an ops vector
   - continue process of reorganization to make libxfs/kernel code
     merges easier
   - refactor the preallocation and hole punching code
   - fix for growfs and verifiers
   - remove unnecessary scary corruption error when probing non-xfs
     filesystems
   - remove extra newlines from strings passed to printk
   - prevent deadlock trying to cover an active log
   - rework xfs_inactive()
   - add the inode directory type support to XFS_IOC_FSGEOM
   - cleanup (remove) usage of is_bad_inode
   - fix miscalculation in xfs_iext_realloc_direct which results in
     oversized direct extent list
   - remove unnecessary count arg to xfs_iomap_write_allocate
   - fix memory leak in xlog_recover_add_to_trans
   - check superblock instead of block magic to determine if dtype field
     is present
   - fix lockdep annotation due to project quotas
   - fix regression in xfs_node_toosmall which can lead to incorrect
     directory btree node collapse
   - make log recovery verify filesystem uuid of recovering blocks
   - fix XFS_IOC_FREE_EOFBLOCKS definition
   - remove invalid assert in xfs_inode_free
   - fix for AIL lock regression"

* smaller runs are dropped. When the freemap doesn't show enough space

* still don't have enough space, then we have to split the block. The
* name/value structs (both local and remote versions) must be 32bit aligned.

* Since we have duplicate hash keys, for each key that matches, compare

* to work "forw"ard. If none matches, continue with the "forw"ard leaf
* nodes until the hash key changes or the attribute name is found.
*
* We store the fact that an attribute is a ROOT/USER/SECURE attribute in
* the leaf_entry. The namespaces are independent only because we also look
* at the namespace bit when we are looking for a matching attribute name.
