locks over clustered filesystem supported now by nfs server

[Steven French]

NFS support for locking over e.g. cluster filesystem just went into 
mainline kernel today.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fd85b8170dabbf021987875ef7f903791f4f181e

Reminds me that it would be nice for them to leverage ctdb if that were 
possible (seems unlikely).

Now if I could figure out the exportfs operations we could have them 
export nfsd over cifs to Samba (of course a dangerous idea, but probably 
no worse than nfs over some of the poorer cluster filesystems today).
