Hello.

Tetsuo-san:

We are discussing about removal of %n support from vsnprintf() at
https://lkml.org/lkml/2013/9/16/52 , and you are using %n in seq_printf().

Well, I'm not using (mere alcohol isn't using, right?)
but I still have the same question for Al.

Are there any races here?

I posted https://lkml.org/lkml/diff/2013/9/19/53/1 which introduces
seq_setwidth() / seq_pad() which can avoid use of %n in seq_printf().

I still think adding last_len, last_rtn
is sensible.
