  sched_ext: Handle cases where pick_task_scx() is called without preceding balance_scx() (2024-11-09 10:43:55 -1000)

sched_ext: Fixes for v6.12-rc7

- The fair sched class currently has a bug where its balance() returns true
  telling the sched core that it has tasks to run but then NULL from
  pick_task(). This makes sched core call sched_ext's pick_task() without
  preceding balance() which can lead to stalls in partial mode. For now,
  work around by detecting the condition and forcing the CPU to go through
  another scheduling cycle.

- Add a missing newline to an error message and fix drgn introspection tool
  which went out of sync.

----------------------------------------------------------------
