--------------------------------------------
syz-executor285/3540 is trying to acquire lock:
ffff888029235378 (&ctx->cq_wait){....}-{2:2}, at: __wake_up_common_lock kernel/sched/wait.c:137 [inline]
ffff888029235378 (&ctx->cq_wait){....}-{2:2}, at: __wake_up+0xfd/0x1c0 kernel/sched/wait.c:160

but task is already holding lock:
ffff888029235378 (&ctx->cq_wait){....}-{2:2}, at: __wake_up_common_lock kernel/sched/wait.c:137 [inline]
ffff888029235378 (&ctx->cq_wait){....}-{2:2}, at: __wake_up+0xfd/0x1c0 kernel/sched/wait.c:160

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(&ctx->cq_wait);
  lock(&ctx->cq_wait);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
