ZNS has superseded OCSSD/lightnvm. As a result, the hardware and software development around OCSSD have also moved on to ZNS. To my knowledge, there is not anyone implementing OCSSD1.2/2.0 commercially at this point, and what has been deployed in production does not utilize the Linux kernel stack.
I do not mind continuing to keep an eye on it, but on the other hand, it has served its purpose. It enabled the "Open-Channel SSD architectures" of the world to take hold in the market and thereby gained enough momentum to be standardized in NVMe as ZNS.
Would you like me to send a PR to remove lightnvm immediately, or should we mark it as deprecated for a while before pulling it?
Best, Matias
