[Qemu-block] [PATCH v2 00/10] Misc reopen-related patches |

Hi,
as part of my blockdev-reopen work here's a new set of patches. This
doesn't implement yet the core functionality of the new reopen
command, but it does fix a few things that help us pave the way.
I believe that the next series after this one will be the last.
The main change is the removal of child references from the options
and explicit_options QDicts. This was already discussed in the
previous series[1], and here's the implementation.
Regards,
Berto
