Then how does the networking code handle the namespace stuff in sysfs? That seems to work today, or am I missing something? If the namespace support needs to be fixed up in sysfs (or in securityfs), then great, let's do that, and not write a whole new filesystem just because that's not done. Also this patch series also doesn't handle namespaces, so again, I am totally confused as to why this is even being discussed... thanks, greg k-h
