I believe the following `Fixes` tag is appropriate, as this commit introduced
the WARN_ON that now triggers:
  
Fixes: d94671632572 ("RDMA/rxe: Rewrite rxe_task.c")
  
However, I'm not entirely certain if this race condition also existed
before this commit, as it involved a significant rewrite.

Thanks
Zhijian
