Re: [PATCH 2/2] NFS: handle IPv6 addresses in nfs ctl

Hi Aurelien,

Again, a few more comments.

I might just modify these in my own tree and send out a patch that 
combines both into one, it might be less work.

This should be:

	in6 = &sin6_storage;

Extra () here.

This should be:

	in6 = &sin6_storage;
