As we all agreed on this, may be it is time to send patches one-by-one?
For the beggining, I propose to resend Cedric's empty namespace patch as base 
for others - it is really empty, but necessary in order to move further.

After this patch and the following net namespace unshare patch will be 
accepted, I could send network devices virtualization patches for review and 
discussion.

What do you think?
