I think you missed the point... the problem with new mount options is
that they need to be specified explicitly in the userspace code for
mount as well as in the filesystem code.

This is actually an elegant idea... allow /proc/filesystems to
specify a list of textual names for options and their corresponding
binary flag values. This makes adding new mount options a non-issue
from the point of view of the mount program: if it sees an option it
doesn't recognize, it checks the appropriate /proc/filesystems line to
see if that specifies it.

Just ideas,
Adam
