Subject: [PATCH v2 1/2] RDMA/rxe: change variable and function argument to proper type
Date: Mon,  7 Mar 2022 22:50:46 +0800	[thread overview]
Message-ID: <20220307145047.3235675-1-cgxu519@mykernel.net> (raw)

The type of wqe length is u32 so in order to avoid overflow
and shadow casting change variable and relevant function argument to
proper type.
