Nice, but incomplete. What we need to add is
* procfs-specific file_operations shared by all regular files
on procfs. Stuff in there would call methods from pde->proc_fops,
after having done the same kind of exclusion you are currently doing
in proc_file_read(), et.al.
* always set ->f_op of regular files on procfs to that sucker.
Don't reset it to NULL during removal.
* now that exclusion is done in wrappers, no need to do it in
proc_file_read().
That'll solve the rest of issues. Eventually we might want to divorce
->proc_fops from file_operations (and trim it down), but that's a separate
story.
