The bugs should now be fixed in Linus's tree due to a fix from Kay,
right?

The user visable behavior change, I missed that, sorry, that is a
regression, do you think it's a big deal to fix in 2.6.27?

I have no problem taking all of these patches as I did this original
work and don't want to burden Jens with this.  Also, I'd like to work
off of the klist changes and class changes as that can be used in other
work that I want to do in the driver core.

Jens any objection to me taking them?  Do you also have changes in this
area that this needs to be merged with?

thanks,
