Hi Jeff, I have a new set that applies on top of 3.16-rc2... but before posting, I wasn't sure what needs to be converted w/regard to blk_mq_alloc_request. As far as I can tell, the new multi-queue block IO queueing implementation via blk_mq_alloc_request should be safe from this bug as it doesn't include any dead queue checks that introduce early exits.
