ReiserFS, from at least version 3, implemented extended attributes (xattrs) as directories, meaning that there were no arbitrary limits. I never understood why other FSes didn't do the same, as it surely makes the code simpler than having a special fixed-size implementation. However, having thought about ResierFS, the idea of xattrs themselves seem pretty odd, because what is data and what is metadata can depend on context, plus of course you're never going to get all the metadata out of files and into FS attributes; and it seems odd to have two different fundamental APIs (regular file API and xattr API) to manipulate different instances of the same on-disk representation (files in directories).
