Merge tag 'sched_ext-for-6.17-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext fix from jun Heo:
 "This contains a fix for sched_ext idle CPU selection that likely fixes
  a substantial performance regression.

  The scx_bpf_select_cpu_dfl/and() kfuncs were incorrectly detecting all
  tasks as migration-disabled when called outside ops.select_cpu(),
  causing them to always return -EBUSY instead of finding idle CPUs.

  The fix properly distinguishes between genuinely migration-disabled
  tasks vs. the current task whose migration is temporarily disabled by
  BPF execution"
