Again: Discard splitting, merging, and coalescing is coming. I'm working on it. It's not exactly trivial. My objection was purely wrt. nuking realtime discard in favor of scrubbing. We absolutely need both approaches. But I'm not going to let crappy SSD firmware implementations set the direction for what I'm working on. It is much more interesting to ensure that we work well for the devices that'll be shipping 6-12 months from now (at the time where this stuff will realistically end up in distro kernels). -- Martin K.
