Hi Yan-

Thanks for letting us know about this.  If that patch is required for
all trees that carry a backport of 777d738 (ceph: fix message length
computation), then we'll need to apply 1f041a89b4 to:

  3.19.y-ckt (stable)
  3.16.y-ckt (stable)
  ubuntu-vivid
  ubuntu-utopic

For our reference, can you point me to a bug report or email thread
which discusses the breakage?
