[Qemu-devel] [PATCH v4 0/6] qemu-io: UI enhancements

[Eric Blake]

While working on NBD, I found myself cursing the qemu-io UI for
not letting me test various scenarios, particularly after fixing
NBD to serve at byte granularity [1].  And in the process of
writing these qemu-io enhancements, I also managed to flush out
several other bugs in the block layer proper, with fixes posted
separately, such as loss of BDRV_REQ_FUA during write_zeroes [2]

2.7 material, depends on Kevin's block-next:
git://repo.or.cz/qemu/kevin.git block-next
and on my pending "block: kill sector-based blk_write/read"
https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg00557.html

Previously posted as part of a larger NBD series [3] at v3, hence
this series starts life at v4.
