  sched_ext: Documentation: Update instructions for running example schedulers (2024-10-08 08:49:18 -1000)

----------------------------------------------------------------
sched_ext: Fixes for v6.12-rc2

- ops.enqueue() didn't have a way to tell whether select_task_rq_scx() and
  thus ops.select() were skipped. Some schedulers were incorrectly using
  SCX_ENQ_WAKEUP. Add SCX_ENQ_CPU_SELECTED and fix scx_qmap using it.

- Remove a spurious WARN_ON_ONCE() in scx_cgroup_exit().

- Fix error information clobbering during load.

- Add missing __weak markers to BPF helper declarations.

- Doc update.
