[Qemu-devel] [PATCH v3 0/9] block: Add auto-read-only option

[Kevin Wolf <kwolf@redhat.com>]

See patch 2 for an explanation of the motivation.

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
