This does not apply against mainline, so I assume this malformatted
thing comes from Christophs seq_read_iter changes in -next.
The seq_read_iter here makes no sense whatsoever if the same thing can
be achieved by using
+DEFINE_SHOW_ATTRIBUTE(debug_stats);
and fixing it at the generic level.
Thanks,

Because the swicth from seq_read to seq_read_iter would rather be
implemented in macro or coccinelle script as you mentioned in another
mail, I can send a new patch against mainline instead if you don't mind.
Thanks.
