  XFS uses 64-bit inodes being mounted without inode64 option

Status in “linux” package in Ubuntu:

Bug description:
  After upgrade from 12.04 XFS became to use 64bit inodes, despite the
  fact that it is mounted without inode64 option:

  root@nfs:~# mount | grep /raid
  /dev/sdb1 on /raid type xfs (rw,noatime,nodiratime,largeio,logbufs=8,allocsize=64m,logbsize=256k,osyncisdsync,nobarrier)

  Volume size is 11TB that is much less than 16TB limit for 32bit

  root@nfs:~# df -h /raid
  Filesystem      Size  Used Avail Use% Mounted on
  /dev/sdb1        11T  3,3T  7,7T  31% /raid

  But there are files wih 64bit inodes on this volume, e.g.:

  root@nfs:~# stat /raid/home/nz/.ssh
    File: ‘/raid/home/nz/.ssh’
    Size: 122       	Blocks: 0          IO Block: 5242880 directory
  Device: 811h/2065d	Inode: 25788470353  Links: 2
  Access: (0700/drwx------)  Uid: (30051/nz)   Gid: (  513/Domain Users)

  All such files are created after 12.04 -> 14.04 upgrade.

  There is a plenty of 32-bit old software that could not access files
  with 64-bit inodes, and it seems that the only option is to recreate
  the whole volume with ext4 filesystem instead of xfs.

  root@nfs:~# lsb_release -rd

  Release:	14.04
