Now that [1]sched_ext was upstreamed into the mainline Linux kernel as part of [2]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.

[3]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 [4]this change by Jose Fernandez that was merged yesterday.
