  sched/deadline: Don't count nr_running for dl_server proxy tasks (2025-08-26 10:46:01 +0200)

----------------------------------------------------------------
- Fix a stall on the CPU offline path due to mis-counting a deadline server
  task twice as part of the runqueue's running tasks count

- Fix a realtime tasks starvation case where failure to enqueue a timer whose
  expiration time is already in the past would cause repeated attempts to
  re-enqueue a deadline server task which leads to starving the former,
  realtime one

- Prevent a delayed deadline server task stop from breaking the per-runqueue
  bandwidth tracking

- Have a function checking whether the deadline server task has stopped,
  return the correct value

----------------------------------------------------------------
Huacai Chen (1):
      sched/deadline: Fix dl_server_stopped()

Juri Lelli (1):
      sched/deadline: Always stop dl-server before changing parameters

Yicong Yang (1):
      sched/deadline: Don't count nr_running for dl_server proxy tasks

kuyo chang (1):
      sched/deadline: Fix RT task potential starvation when expiry time passed
