[1]Linux 6.12 is shaping up to be a heck of a kernel update! Following [2]real-time "PREEMPT_RT" going mainline after twenty years and many other kernel features merged this week, Linus Torvalds just pulled in the much anticipated sched_ext code!

The [3]sched_ext code for extensible scheduler behavior by allowing scheduling policies to be implemented as BPF programs has been merged. Sched_ext was [4]planning to merge it for Linux 6.11 but [5]that didn't end up happening . Earlier in the week [6]necessary scheduler changes were made and that paved the way for sched_ext being merged today.

Sched_ext has seen much interest and usage already within patched kernels for its long out-of-tree state. Sched_ext can allow for some quite innovative scheduling scenarios from gaming [7]to other scenarios .

With much delight, a few minutes ago sched_ext was [8]merged . The committed [9]documentation provides more insight for those interested in the sched_ext prospects.

Also merged today were the [10]BPF updates for Linux 6.12.
