I'd like to queue this for 4.20. > That was the v1 patch description, which had multiple issues. The problem that got carried over is, that we still don't know if it is a bug-fix or just a readability improvement. In the v1 discussion I questioned this being a bugfix, but we never finished the discussion because of KVM Forum. Anyway, the new commit message does not read as bad (although I would drop 'which could be used' and if it isn't a bugfix also explain that the code was ok -- if it is a bugfix shouldn't we cc stable?). Connie, if you don't feel like figuring out the bug or not question, feel free to just add an Ack by me and queue for 4.20. Regards, Halil
