Hm, but how are these ifdefs even related to the coroutine conversation? It's a bit more code that you're moving around, but shouldn't it be unchanged from the old code, just moving from an AIO callback to a coroutine? Or am I missing some complications? > Would it be an option to make a big ifdef in the rbd driver? One with > old code for < 12.0.0 and one > > with new code for >= 12.0.0? I don't think this is a good idea, this would be a huge mess to maintain. The conversion is probably a good idea in general, simply because it's more in line with the rest of the block layer, but I don't think it adds anything per se, so it's hard to justify such duplication with the benefits it brings.
