This value is already exported via procfs:
sockstat_seq_show() -> socket_seq_show().
And the proc file itself should already be per-net:
static int sockstat_seq_open(struct inode *inode, struct file *file)
{
return single_open_net(inode, file, sockstat_seq_show);
}
This patch just makes that value to be per-net too.
