[Qemu-block] [PATCH 00/14] Don't pass flags to bdrv_reopen_queue()

[Alberto Garcia]

Hi,

in the description of my "Misc reopen-related patches" I said that the
next series after that one would be the implementation of the
blockdev-reopen QMP command. That's not going to be the case after all
because I have a dozen of new patches that I wanted to publish now.

So here's what's going on:

When reopening a BlockDriverState using bdrv_reopen() and friends the
new options can be specified either with a QDict or with flags. Both
methods overlap and that makes the semantics and the implementation
unnecessarily complicated.

This series removes the 'flags' parameter from these functions, so
from now on all option changes must be specified using a QDict. Apart
from simplifying the API, a few bugs are fixed along the way. See the
individual patches for more details.

This needs to be applied on top of "Misc reopen-related patches v3"
(https://lists.gnu.org/archive/html/qemu-block/2018-09/msg00103.html),
which goes on top of the current master (19b599f7664b2ebfd0f405fb79c).

Regards,

Berto
