Server-side support for NFSv4 named attributes #6

This was bugzilla.linux-nfs.org 55

[J. Bruce Fields 2005-08-26 11:55:06 UTC] We don't currently support NFSv4's named attributes.

The current VFS interface for extended attributes is a poor match for NFSv4 named attributes, which are more like first-class file objects. So some VFS changes will be required. See Rieser4-related discussions on LKML, especially messages from Viro and others which give some implementation suggestions for a new VFS interface.

[J. Bruce Fields 2022-01-07 22:12:45 UTC] Speculative named attribute interface is not in the works. Nobody is working on it, upstream discussions have not shown much appetite for it.

Now have user xattrs which may handle some of same use cases.

There was another request for named attribute support recently. Two local file systems that support these are NTFS3g (in tree) and ZFS (not in tree). However, there is no VFS plumbing to access these at this time.
