It doesn't need to. This helps out the code. seq_buf has nothing to do
with seq_file (yet).

But this code comes from the trace_seq internals. It's a way to combine
the code between seq_file and trace_seq. It is influenced by seq_file,
but the code is trace_seq. Actually, this patch set has nothing to do
with seq_file and finishes up solving a problem with printks dump
stacks from NMIs.
Look at the path of the seq_buf.c code.

Why? I'm the one that is maintaining it. It's going to go through my
tree and it has almost all the acks I need.
I will say the first 13 patches have already been acked and reviewed,
and are going to be going into my for-next queue soon. I'll be posting
a smaller set with the patches that changed.
Well, all but the last 3 patches. Those are the ones that I'm going to
work with Linus and Andrew on before I pull them into my tree.
