A notice just went out to the ols-announce mailing list that said:
This year we have one tutorial with limited attendance that people will need to sign up for in advance. Greg Kroah-Hartman will be doing a tutorial where you Write a Real, Working Linux Driver and there are 30 spaces for participants.
The tutorial also has a hardware cost for the USB device for which you will be writing a driver of $40 CAD. Please bring it with you to the tutorial.
Please see the requirement of the attendees as listed here.
If you want to reserve a space, please send me an email.
I think the tutorial is going to be scheduled on the second day of the conference, in the morning, but as the schedule is not finalized, I can not be sure.
