This looks fishy:

  cloned_file = clone_filp(file); /* clone the file */
  list_move(&cloned_file->f_list, &sb->s_files);

I don't see where you initialized the ->f_list of the cloned file.

This is a really bad idea:

+   /* wait a bit, in hopes that the processes will take
+    * their errors, close out their files (and hope
+   schedule_timeout(5*HZ);

It's only going to make you miss bugs that will rear their heads later, 
never mind the extra time 5 seconds it leaves the poor admin wringing 
their hands.

Sorry, I only had time for a superficial look.  It's challenging, to say 
the least.
