[Qemu-devel] [PULL 09/21] migration: Use normal VMStateDescriptions for Subsections |
|
Date: |
Wed, 3 Jun 2015 14:05:45 +0200 |
We create optional sections with this patch. But we already have
optional subsections. Instead of having two mechanism that do the
same, we can just generalize it.
For subsections we just change:
- Add a needed function to VMStateDescription
- Remove VMStateSubsection (after removal of the needed function
it is just a VMStateDescription)
- Adjust the whole tree, moving the needed function to the corresponding
VMStateDescription
