Applied, thanks.
General question for Matias - is lightnvm maintained anymore at all, or
should we remove it? The project seems dead from my pov, and I don't
even remember anyone even reviewing fixes from other people.
Hi Jens,
ZNS has superseded OCSSD/lightnvm.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
