The polling is stopped after a +AD4 predefined timeout (1/2 sec by default). +AD4 Support for all interrupt driven mode is planned, and it shows promising results. Which cgroup will the CPU cycles used for polling be attributed to? Can the polling code be moved into user space such that it becomes easy to identify which process needs most CPU cycles for polling and such that the polling CPU cycles are attributed to the proper cgroup? Thanks, Bart.
