Hmm, one thing that I've mentioned to you before though is that some options 
(like update) aren't mount options, they are flags to the mount() syscall 
that explain how to apply the list of options.  Those sort of flags don't 
really belong in the mount options list it seems to be, but in a 
separate "flags" argument to nmount() itself.

That would also remove the need for having the kernel weed out these options 
(force/update/etc.) from the mount options list by not having them there in 
the first place.  I think having mount operation flags passed separately from 
mount options is going to be a less bug-prone and more stable approach.
