Hi!

(ingoring the fact your opinion may be influenced by SUSE/Novell)

Are you saying that SUSE/Novell added bugs regarding NFS4 that are not present in 
the vanilla kernel, or are you saying that the vanilla kernel may have fixed NFSv4 
bugs that SUSE/Novell did not fix? Why shouldn't anybody be interested in the fact 
that there are problems?

Regards,
Ulrich
