Try <http://web.gnu.walfield.org/mail-archive/linux-fsdevel/>. That's the
only archive I found that also keeps older messages.

This would favor implementing one of the other UNIX vendor RPC extensions.
I have no problem with integrating such changes in the kernel patch and/or
adding a patch for user space NFS to the Web site, provided that's what
you want to do.

Note that NFSv2 can't support ACLs at all, as clients make access control
decisions based on the file mode permission bits. NFSv3 works because it
uses an RPC to check whether access is granted.

Andreas
