  sched: Fix race in task_call_func() (2022-11-14 09:58:32 +0100)

----------------------------------------------------------------
- Fix a small race on the task's exit path where there's a
misunderstanding whether the task holds rq->lock or not

- Prevent processes from getting killed when using deprecated or unknown
rseq ABI flags in order to be able to fuzz the rseq() syscall with
syzkaller

----------------------------------------------------------------
Mathieu Desnoyers (1):
      rseq: Use pr_warn_once() when deprecated/unknown ABI flags are encountered

      sched: Fix race in task_call_func()
