[Pvfs2-users] NFS support status?

[Phil Carns]

Hi Emmanual,

I haven't had a chance to look at what specifically went wrong with NFS 
access in this case, but I think in general there is an issue with how 
NFSv4 expects us to use iget to resolve inodes.

I suspect it will be fragile unless we implement the file handle 
functions described here:
