Merge tag 'for-linus-v3.11-rc1' of git://oss.sgi.com/xfs/xfs

Pull xfs update from Ben Myers:
 "This includes several bugfixes, part of the work for project quotas
  and group quotas to be used together, performance improvements for
  inode creation/deletion, buffer readahead, and bulkstat,
  implementation of the inode change count, an inode create transaction,
  and the removal of a bunch of dead code.

  There are also some duplicate commits that you already have from the
  3.10-rc series.

   - part of the work to allow project quotas and group quotas to be
     used together
   - inode change count
   - inode create transaction
   - block queue plugging in buffer readahead and bulkstat
   - ordered log vector support
   - removal of dead code in and around xfs_sync_inode_grab,
     xfs_ialloc_get_rec, XFS_MOUNT_RETERR, XFS_ALLOCFREE_LOG_RES,
     XFS_DIROP_LOG_RES, xfs_chash, ctl_table, and
     xfs_growfs_data_private
   - don't keep silent if sunit/swidth can not be changed via mount
   - fix a leak of remote symlink blocks into the filesystem when xattrs
     are used on symlinks
   - fix for fiemap to return FIEMAP_EXTENT_UNKOWN flag on delay extents
   - part of a fix for xfs_fsr
   - disable speculative preallocation with small files
   - performance improvements for inode creates and deletes"
