Well, I could set it to the &init_struct_pid as you said, but it will not change any of the code below it. So it does not matter what ftrace_swapper_pid is set to, as long as it is not set to something that can be a legitimate pid struct for something not the swapper task. It will only matter when we fix the fork code. > > As for fork. It would be nice to remove most of the special cases > for the idle thread. At least the counts are significant.

That is probably important. -- Steve _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
