Thanks,
The general consensus of everyone who has been involved in the discussion so far, seems to be that the benefits of keeping zstd in-sync with upstream outweigh the cost of accepting upstream’s API, though not everyone agrees. The alternative is to provide a wrapper around upstream’s API, but this makes it slightly harder to debug, since you have to go through the wrapper whose only purpose is to adapt to the coding style, and allows bugs to sneak into the kernel implementation, which aren’t present upstream. Additionally, in 2017 LZ4 switched to using upstream LZ4’s API in order to stay up to date with upstream, which sets precedent. I also help maintain LZ4, and once the zstd update is merged, I plan to work on making it easier to update LZ4 in the kernel when upstream updates. That will be a much smaller change, since LZ4 is already nearly using upstream’s code directly. Best, Nick
