Merge tag 'sched_ext-for-6.17-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext fixes from Tejun Heo:
- Fix build failure when !FAIR_GROUP_SCHED && EXT_GROUP_SCHED
- Revert "sched_ext: Skip per-CPU tasks in scx_bpf_reenqueue_local()"
which was causing issues with per-CPU task scheduling and reenqueuing
behavior
