New Linux Kernel Patches Better Prepare For sched_ext
While Linus Torvalds called for including the 'sched_ext' extensible scheduler in Linux 6.11, he ultimately decided not to merge it for Linux 6.11 after some technical issues were raised on the Linux kernel mailing list.
The good news is that there has been healthy discussion since that point in addressing the problems so that sched_ext will be in shape for merging in a forthcoming kernel cycle. "These patches apply on top of the EEVDF series (queue/sched/core), which re-arranges the fair pick_task() functions to make them state invariant such that they can easily be restarted upon picking (and dequeueing) a delayed task. We'll see if sched_ext manages to be ready by the Linux v6.12 merge window in mid-September or if more time is needed to bake and in turn pushing this extensible scheduler code into a 2025 kernel release.
