> Before this change the logic of matching the devfs paths to the patterns in

> (sorry for tautology).

> Please note that nothing changes with respect to matching simple paths like
> /dev/something.  It is the complex paths that involve subdirectories that are
> affected.

> I think that if you knew how the old logic worked and were able to devise rules
> for it, then you will have no problem to change those rules for the new logic.
> Just please don't forget to do it when you upgrade!
> 
> I hope that overall you will find this change to be an improvement.

> P.S. I notify stable@ because I currently plan to MFC this change after 1 month
