Interval could be a good replacement for mni in the mm/mmu_notififer
file if we don't do the wholesale rename

Well, lets just bite the bullet then and switch it. Do you like

We could use mmnotif as the prefix, this makes the longest:

  struct mmnotif_range_subscription

Which is reasonable enough

I tried this last time I renamed everything, it was OK, but it missed

I'll make some patches next week when I get back.
