Hi Bob,
[auto build test ERROR on v4.3-rc7 -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

Note: the linux-review/Bob-Liu/xen-block-multi-hardware-queues-rings-support/20151102-122806 HEAD b29fe44b095649f8faddc4474daba13199c1f5e0 builds fine. It only hurts bisectibility.
All errors (new ones prefixed by >>):
