The commit 7b2b160da7661bb2ade3f924b1bd3e3084e53341 cherry-picked
cleanly on top of the 3.8 LTS tree.  I assumed it didn't make the
official 3.8 stable branch because it was EOL by the time it was
proposed for stable.  Since we don't see the problem when we are on the
3.5 LTS kernel we didn't try to merge it to this branch.

Title:
  Ubuntu-lts-3.8.0 kernels corrupt ext[234] filesystems with 1k block
  size in Xen guests

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  We observed a problem with a Postfix database file created by postmap becoming corrupted in a Xen guest when the file was on an ext4 filesystem with a 1kb block size.  This was reported to the linux-ext4 list in http://marc.info/?t=138018028300003&r=1&w=2.  The subsequent investigation identified the git commit 7b2b160da7661bb2ade3f924b1bd3e3084e53341 as solving the problem.  We have applied this on top of tag Ubuntu-lts-3.8.0-13.22 and confirmed that it resolves the problem we are seeing.
