From: Klaus Jensen <k.jensen@samsung.com>
This series reimplements flush, dsm, copy, zone reset and format nvm to
allow cancellation. I posted an RFC back in March ("hw/block/nvme:
convert ad-hoc aio tracking to aiocb") and I've applied some feedback
from Stefan and reimplemented the remaining commands.
The basic idea is to define custom AIOCBs for these commands. The custom
AIOCB takes care of issuing all the "nested" AIOs one by one instead of
blindly sending them off simultaneously without tracking the returned
aiocbs.
v2:
- dropped RFC
- fixed flush cancel from being unintentially a noop (Vladimir)
