Sync to vmlinux.h from sched_ext/for-6.11 1edab907b57d ("sched_ext/scx_qmap:
Pick idle CPU for direct dispatch on !wakeup enqueues"). This most likely
will be the commit which will be merged during the upcoming kernel v6.11
merge window.
Unfortunately, this is a compatibility breaking change. As the size of
bpf_iter_scx_dsq is reduced, schedulers that use the iterator - scx_lavd and
scx_layered - won't be able to run on older kernels. Likewise, older
binaries from before this commit won't be able to run on newer kernels.

SCHED_EXT SCHEDULERS
Introduction
This directory contains the repo's schedulers.
Some of these schedulers are simply examples of different types of schedulers that can be built using sched_ext. They can be loaded and used to schedule on your system, but their primary purpose is to illustrate how various features of sched_ext can be used.
Other schedulers are actually performant, production-ready schedulers. That is, for the correct workload and with the correct tuning, they may be deployed in a production environment with acceptable or possibly even improved performance. Some of the examples could be improved to become production schedulers.
Please see the following README files for details on each of the various types of schedulers:
- rust describes all of the schedulers with rust user space components. All of these schedulers are production ready.
- c describes all of the schedulers with C user space components. All of these schedulers are production ready.
Note on syncing
Note that there is a sync-to-kernel.sh script in this directory. This is used to sync any changes to the specific schedulers with the Linux kernel tree. If you've made any changes to a scheduler in please use the script to synchronize with the sched_ext Linux kernel tree:
$ ./sync-to-kernel.sh /path/to/kernel/tree
