oh right. Still trying to get my head around this wrt to mixed
protocol and local access to xattrs, but it looks like I have a
problem here when xattrs are created on the server by other protocols
(or locally on the server):

On the server:
# setfattr -n user.foo -v bar /path/file

On the client (/path mounted from server):
# xattr -p foo /mount/file
ba

bar? baz? :)
