[Qemu-devel] [PATCH v5 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" v7 or later
https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg00895.html

Previously posted as part of a larger v3 NBD series [3] and as a
separate v4 [4], so this is v5.

Changes since then:
- patch 1: add more cleanups (R-b dropped)
- patch 2 (was 5/6) hoist earlier, retitle, use -dMODE instead
of inventing -u [mreitz], add -k and -tMODE
- patch 4 (was 3/6) fix bool usage, drop spurious usage space [mreitz]
- patch 5 (was 4/6) fix bool usage [mreitz]
- patch 6 rebase to earlier changes (R-b kept)
