This code doesn't exist in the above mentioned commit.  But event
without knowing the details of the /proc/net code this looks somewhat
bogus.  For one I thought all the /proc/net files should be per-net
namespace.  Second the ntp file really should be using proc_create_net,
to handle all that under the hood - with the merge of the VFS
tree it will take a seq_ops, which is what this code really wants
anyway.
