Merge tag 'sched_ext-for-6.15-rc0-fixes' of git://git.kernel.org/pub/scm/linux/kernel...

Pull sched_ext fixes from Tejun Heo:

 - Calling scx_bpf_create_dsq() with the same ID would succeed creating
   duplicate DSQs. Fix it to return -EEXIST.

 - scx_select_cpu_dfl() fixes and cleanups.

 - Synchronize tool/sched_ext with external scheduler repo. While this
   isn't a fix. There's no risk to the kernel and it's better if they
   stay synced closer.
