RFC 8276 and your draft (Support for Data Reduction Extended Attributes in nfsv4 Version 2) are the only serious documents that I found about this topic. I would like to know if Extended Attributes have been already implemented somewhere that I can test it out, or If someone try to implement this before or any source code that I can reach out or any draft code? Besides the code portions that appears on RFC 8276.
