AFAIK the SYSFS_DEPRECATED hides the sysfs functionality (files)
that is not recommended to use, but doesn't disable the sysfs
filesystem as is. On the other hand the NET_NS doesn't require 
any deprecated sysfs files, it just can't work at all with the 
SYSFS turned on. 

That's why the things look like this.
