  sched_ext: Use IRQ_WORK_INIT_HARD() to initialize rq->scx.kick_cpus_irq_work (2025-11-17 05:07:22 -1000)

----------------------------------------------------------------
sched_ext: Fixes for v6.18-rc6

Five fixes addressing PREEMPT_RT compatibility and locking issues. Three
commits fix potential deadlocks and sleeps in atomic contexts on RT kernels by
converting locks to raw spinlocks and ensuring IRQ work runs in hard-irq
context. The remaining two fix unsafe locking in the debug dump path and a
variable dereference typo.

----------------------------------------------------------------
Andrea Righi (1):
      sched_ext: Fix use of uninitialized variable in scx_bpf_cpuperf_set()

Emil Tsalapatis (1):
      sched/ext: convert scx_tasks_lock to raw spinlock

Zqiang (3):
      sched_ext: Fix unsafe locking in the scx_dump_state()
      sched_ext: Fix possible deadlock in the deferred_irq_workfn()
      sched_ext: Use IRQ_WORK_INIT_HARD() to initialize rq->scx.kick_cpus_irq_work
