Subject: [Qemu-devel] [PATCH v4 00/11] block: Add auto-read-only option
Date: Fri, 19 Oct 2018 18:30:04 +0200 [thread overview]
Message-ID: <20181019163013.11787-1-kwolf@redhat.com> (raw)
See patch 2 for an explanation of the motivation.
v4:
- Split fix for missing rbd_close() into a separate patch [Eric]
- Added qemu-iotests case
v3:
- Clarified QAPI schema documentation that auto-read-only can only
degrade read-write to read-only, not the other way round [Eric]
- Don't refuse to set copy-on-read=on and auto-read-only=on at the same
time; only complain when actually trying to degrade to read-only
- Let bdrv_apply_auto_read_only() return -EACCESS on all errors
- Fixed file-posix and gluster implementations [Eric, Niels]
- Added a patch to make auto-read-only=on the default for human user
interfaces (-drive/-hda/...)
v2:
- Turn bdrv_set_read_only() into bdrv_apply_auto_read_only()
- Support the option in a lot more block drivers
