Heh, that was quick, I had no time to review :)

The change looks good to me.  Thanks for your fix (and rebasing).

One thing is that you removed bdl_pos_adj=0 check.  This was there
explicitly to avoid the delayed irq handling no matter whether the
value is correct or not.  I guess it's safer to take it back, or
give any other way for user to avoid the delayed irq handling.


thanks,

Takashi
