I don't want to have years of "fix up the mistakes after the fact". This is all done entirely incorrectly, and just as an example of that, subbuf_map_prepare() is another case of "tracing code works around the fact that it did things wrong in the first place". So instead of merging a new feature that was mis-designed and is already having code working around its mis-design, I'm not merging it at all. Linus
