[Qemu-devel] [PATCH v7 00/19] block: kill sector-based blk_write/read

[Eric Blake <eblake@redhat.com>]

2.7 material, depends on Kevin's block-next:
git://repo.or.cz/qemu/kevin.git block-next

Previously posted as part of a larger NBD series [1] and as v6 [3].
Mostly orthogonal to Kevin's recent work to also kill sector
interfaces from the driver.

git fetch git://repo.or.cz/qemu/ericb.git nbd-block-v7

changes from v6:
- drop unrelated patch 2 [kwolf]
- patch 4/19 (was 5): use 'qiov' name [kwolf], bump copyright year
- patch 6/19 (was 7): drop another dead 'n' variable, tweak comment
wording [kwolf]
- patch 16/19 (was 17): add new define for MBR_SIZE [kwolf]
