If you're going to work on it, please give a patch series and let me
merge once.  There is no good merit to merge a half-baked piece by
piece.

Regarding the changes you've made: so far, I've merged two such
patches just because it's a good exercise for newbies.  You've played
it and experienced it enough.  So it's time to go up to a higher
stage, more "real" fixes.

For example, if you are still interested in printk stuff, try to
change the calls to dev_err() and co.  Of course, this needs more
understanding of the code you'll handle, which object is passed for
which messages.


thanks,

Takashi
