Well, /proc/mounts is a bit more than just for the interest of the
user.  It should contain _all_ mount options that are necessary to be
able to reconstruct the mount.

Only those options need not be shown that have a one-time permanent
effect on the underlying filesystem (e.g. creating a journal file).
All other options should be shown, whether they are per-sb or are
shared between multiple superblocks.
