[PATCH v4 0/6] Allow changing bs->file on reopen


From: Alberto Garcia
Subject: [PATCH v4 0/6] Allow changing bs->file on reopen
Date: Wed, 17 Mar 2021 18:15:51 +0100

Based-on: <20210317143529.615584-1-vsementsov@virtuozzo.com>

Hello,

this is the same as v3, but rebased on top of Vladimir's "block:
update graph permissions update v3", which you can get here:

git: https://src.openvz.org/scm/~vsementsov/qemu.git
tag: up-block-topologic-perm-v3

Tip: you may find it easier to review patch 4 if you use 'git diff -w'
since a big part of the changes that you see in
qmp_x_blockdev_reopen() are just indentation changes.

Berto

v4:
- Rebase on top of version 3 of Vladimir's branch
v3: https://lists.gnu.org/archive/html/qemu-block/2021-03/msg00553.html
v2: https://lists.gnu.org/archive/html/qemu-block/2021-02/msg00623.html
v1: https://lists.gnu.org/archive/html/qemu-block/2021-01/msg00437.html

Output of git backport-diff against v3:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
