[Qemu-block] [PATCH v4 0/3] Clean unused entries in the qcow2 L2/refcount cache

[Alberto Garcia]

v4:
- Revert the 'cache-clean-interval' change. This should probably go
  into a new BlockDeviceInfoSpecific struct (along with other
  settings), but is out of the scope for this series.

v3: https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg05473.html
- Add 'cache-clean-interval' field to ImageInfoSpecificQCow2.

v2: https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg05316.html
- Clarify that the block-commit mentioned in the first patch refers to
  the HMP commit command.
- Check the value of cache_clean_interval and cast it accordingly to
  prevent it from overflowing.

v1: https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg03510.html

Regards,

Berto
