Fedora's Kernel Build Now Enabling Sched_Ext Support

Now that sched_ext was upstreamed into the mainline Linux kernel as part of the many great features in Linux 6.12, Fedora's kernel builds are prepared to enable this innovative scheduler feature that allows for new scheduling policies to be loaded via (e)BPF programs.

CONFIG_SCHED_CLASS_EXT is now enabled for Fedora's Linux 6.12+ kernel builds moving forward. The Fedora ARK kernel now has sched_ext enabled and will be coming into Fedora Rawhide while for those riding stable Fedora releases will then premiere with Fedora Linux 42.

Sched_ext allows for some nifty Linux kernel scheduler innovations and has long been sought after for the mainline kernel with already developing a following in its former out-of-tree state.

The extensible scheduler class for the Fedora kernel builds was enabled via this change by Jose Fernandez that was merged yesterday.
