Subject: [Qemu-devel] Re: [PATCH +stable] block: don't attempt to merge overlapping requests

I just caught up on mails and saw you had already mentioned that
overlapping writes from the guest look fishy in the "the >1Tb block
issue". Cache mode might still be interesting because it affects how
guest virtio-blk chooses queue ordering mode.
