Downstream packaging changes are tracked in the .spec file's changelog.

Since Kernel 2.6.38 was released, autogroup schedule patch has been merged into mainline kernel. I rememberd Lennert Poettering argued on autogroup schedule with Linus Torvalds. The patch is just working with processes from TTY console. Lennert seemed to tell us the best way was that init system provided autogroup schedule. Now systemd is able to give every service, every user and every user session own cgroup in the CPU hierarchy. How far is autogroup schedule in systemd from us? I can not hear any news about it. I know this is not easy job because every process has its own property. But I hope it is coming soon and really makes our desktop more smooth. We cannot do per-application 'cpu' grouping yet, since systemd is currently not used for managing user applications as session manager (we are looking into doing this for F16 however). Per-service 'cpu' grouping is on by default in F15. Per-user 'cpu' grouping we had to disable since the kernel is currently too limited, and enabling this means that RT scheduling will not be available for the user. If you do not care for RT you can enable per-user 'cpu' grouping by editing /etc/pam.d/system-auth and adding controllers=cpu to the configuration line of pam_systemd. See pam_systemd(8) for more information. Per-Terminal grouping is not available, but there's a patch for gnome-terminal in gnome bz for that. But we probably should get per-application grouping right before we think about this. Given that this is how it is the F15 kernel will have setsid()-based autogrouping enabled.
