It'd have been nicer if you'd have cc'd me.

What I submitted is far simpler and it allows a knob
to control the printk buffering on a global basis.

Did you try it?  It seems to work here, but I don't
have your other patches to rcu-torture with inserted
printk_flush patches to verify it.  Can I have a
copy of those please.
