is support planned for user.* xattrs?

[Joshua Hoblitt]

Hello,

I'd like to start by apologizing for sending this message to a
development list.  The documentation (wiki, etc.) don't make it
clear if user xattrs are currently supported or not but seem suggest that
such functionally is at least planned.  I decided it give it a try 
with the nfsv4 implementation as shipped with 2.6.19.  Indeed, only
ACL xattrs are supported.  Looking through nfs4proc.c in 2.6.21 confirms
that there is no support of xattrs beyond what is necessary for ACLs.

So I guess my questions are: Is there any design issue that prevents
user xattrs from being implemented in mainline?  Is there a patch
floating around some where that supports this already?  Alternatively,
is there any one else interested in this functionality?

Cheers,

-J
