This series is for two minor virtio-blk changes. The first patch
makes the virtio-blk queue size user configurable. The second patch
rejects logical block size > physical block configurations (similar
to a recent change in virtio-scsi).

Depending on the configuration, it can be beneficial to adjust the virtio-blk
queue size to something other than the current default of 128. Add a new
property to make the queue size configurable.

virtio-blk logical block size should never be larger than physical block
size because it doesn't make sense to have such configurations. QEMU doesn't
have a way to effectively express this condition; the best it can do is
report the physical block exponent as 0 - indicating the logical block size
equals the physical block size.
This is identical to commit 3da023b5827543ee4c022986ea2ad9d1274410b2
but applied to virtio-blk (instead of virtio-scsi).

Please see commit 9b02e1618cf26aa52cf786f215d757506dda14f8 ("virtio-net:
enable configurable tx queue size") for additional considerations.
QEMU's virtio implementation hardcodes the maximum queue size at 1024
and this limit must be checked.

Hi Mark,
Please resend as a top level email thread so the continuous integration
and patch management tools will detect your patch series.
From https://wiki.qemu.org/Contribute/SubmitAPatch:
"Send each new revision as a new top-level thread, rather than burying
it in-reply-to an earlier revision, as many reviewers are not looking
inside deep threads for new patches."
Thanks,
Stefan
