We may need to make sure they can't be changed to write as well. But that
will require a change to tracefs (and eventfs).  

Ah, you mean the permission check is not correctly done in tracefs/eventfs yet?

Actually, i think we could use a different fops for read only instances
that do not have a write callback. And for eventfs we could have it for
read only instances to only create the id and format files.
