http://www.usenix.org/events/was going to be in Ottawa, Canada, is now in my local city, Cambridge UK.
"For the sixth year, USENIX will present the annual Linux Kernel Developers Summit, bringing together the core of the Kernel development team to plan the next phase of Linux Kernel development. Like past Summits, this developer-to-developer, two-day event delivers substantive technical sessions and workshops where developers and industry leaders can readily share and exchange ideas. This event seeks to further feature development that brings Linux into enterprise class and highly available computing environments.
Participation at the Summit is by invitation only"
