   I dunno when it happened, but 2.5.x now returns EINVAL for all 
   file->file cases.
   
   In 2.4.x, if sendpage is NULL, file_send_actor in mm/filemap.c faked a 
   call to fops->write().
   In 2.5.x, if sendpage is NULL, EINVAL is unconditionally returned.
   

What if source and destination file and offsets match?

The same data is written out.  No deadlock.
(unless the attached test is wrong)
