Subject: [PATCH v2 00/33] block: Introduce real BdrvChildRole
Date: Tue, 4 Feb 2020 18:08:15 +0100 [thread overview]

Branch: https://git.xanclic.moe/XanClic/qemu.git child-role-v2
v1: https://lists.nongnu.org/archive/html/qemu-block/2019-11/msg00908.html
Hi,
For the “why” and “what” regarding this series, see the cover letter of
v1 (linked above).
v2:
- Dropped BDRV_CHILD_STAY_AT_NODE from BdrvChildRole
- Dropped BDRV_CHILD_PROTOCOL and BDRV_CHILD_FORMAT from BdrvChildRole;
this necessitates a BlockDriver.is_format flag that
BdrvChildClass.inherit_options() receives and from which (and the
BdrvChildRole) it can figure out whether to set, clear, or bequeath
BDRV_O_PROTOCOL.
- Document that BDRV_CHILD_PRIMARY must be set for at most one child at
a time.
- Rebasing conflicts with the compress filter
- Split “block: Unify bdrv_*inherited_options()” into three patches (8
through 10)
- Dropped the old patch 6 (“Keep BDRV_O_NO_IO...”) because it
effectively didn’t do anything (child_file.inherit_options() still
cleared BDRV_O_NO_IO). Implicitly do the change in patch 10 instead
and explain it in the commit message.
