Subject: Re: [PATCH] RDMA/siw: Reuse value read using READ_ONCE instead of re-reading it

I want to emphasize that if the value of orqe->flags has changed by the
time of the second read, the value read will not satisfy the if condition,
causing inconsistency. Given that there is already a READ_ONCE.
