x-blockdev-reopen is still considered unstable upstream. libvirt needs
|
|
|
902636 |
(a small subset of) it for incremental backups, though.
|
|
|
902636 |
|
|
|
902636 |
Add a downstream-only feature flag that effectively makes this a
|
|
|
902636 |
versioned interface. As long as the feature is present, we promise that
|
|
|
902636 |
we won't change the interface incompatibly. Incompatible changes to the
|
|
|
902636 |
command will require us to drop the feature flag (and possibly introduce
|
|
|
902636 |
a new one if the new version is still not stable upstream).
