attributes to NFSv4 and I would like if you can send me in the right =
direction. 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.
