You are more familiar with NFS, so I think it would be better if you
updated nfs_show_mount_options().
Could you also queue my patch (updated) or incorporate it into a
combined fix?

Subject: mount options: partially fix nfs
From: Miklos Szeredi <mszeredi@xxxxxxx>
Add posix, bsize=, namelen= options to /proc/mounts for nfs
filesystems.
Document several other options that are still missing.
Changes:
- display namelen= unconditionally
- addr= isn't missing after all
