Hi all!
On the way of backup schemes development (and in general any complicated
developments in Qemu block layer) it would be good to have a way to print
out graph of block nodes with their permissions. Here is this way.
Instead of a lot of words I'll reply to this cover letter with example
graph, generated in patch 04.
Vladimir Sementsov-Ogievskiy (4):
block: improve blk_root_get_parent_desc
qapi: add x-query-block-nodes-relations
scripts/qemu: add render_block_graph method for QEMUMachine
not-for-commit: example of new command usage for debugging
