Hello all,

This is advance notice of $subject [1] for out of tree virt driver
maintainers. While working on a bugfix [2] I noticed that the original
legacy block_device_info dict format [3] hasn't been used by any in-tree
drivers since xenapi was dropped in Victoria [4]. As a result I will be
looking to remove support for the format during Xena unless any out of
tree drivers come forward with issues.
