at least we have preemption out of printk->user way (one of the
things I tried to tell you), which looks more like a step forward
to me personally.


p.s. the printk is still pretty far from what I want it to be.
     vprintk_emit() still can cause disturbance and damage in
     pretty unrelated places. e.g. hung tasks on console_sem,
     and so on. I'm going to keep my out-of-tree patches alive,
     may be they will be merged upstream in some form or another
     may be not.
