[Qemu-devel] [PATCH 00/14] block jobs: Convert I/O to BlockBackend

[Kevin Wolf <kwolf@redhat.com>]

This series changes the block jobs so that they have a separate BlockBackend
for every node on which they perform I/O. This doesn't only get us closer to
the goal of only doing I/O through blk_*() from external sources (and block
jobs are considered external), but can also later be used to use BlockBackend
features for jobs: One could imagine replacing the very basic job throttling by
the already existing and more advanced BlockBackend throttling, or using the
BlockBackend error handling for block jobs.

This depends on the following queue of series on top of block-next:
* [PATCH v2 00/13] block: Move I/O throttling to BlockBackend
* [PATCH v2 0/9] block: Remove BlockDriverState.blk
* [PATCH v3 for-2.7 0/8] blockdev: (Nearly) free clean-up work
