** Description changed:

+ ====================================
+ SRU Justification:
+ 1. Impact: very slow rbd volumes
+ 2. Test case: see below (create an RBD volume and check the stripe unit and 
count)
+ 3. Regression potential: the patch simply fixes the argument order in a fn 
call and does nothing else, so there should be no regressions.
+ ====================================
+ 
  Copied from upstream bug at
  https://bugzilla.redhat.com/show_bug.cgi?id=1092208:
  
  "When creating an RBD volume with 'virsh vol-create-as', the newly
  created volume gets a stripe unit of 1 byte and a stripe count of
  4194304. This results in an RBD volume which is unusably slow (in my
  tests, it took over 30 minutes for GRUB to load in an affected guest)."
  
  This bug has been fixed upstream for libvirt 1.2.4, but the fix has not
  been backported for trusty-updates. This means this functionality is
  broken and unusable in the current LTS.
