smatch warning this:
net/sunrpc/xprtrdma/svc_rdma_rw.c:351 svc_rdma_post_chunk_ctxt() error: uninitialized symbol 'bad_wr'
net/sunrpc/xprtrdma/verbs.c:1569 rpcrdma_post_recvs() error: uninitialized symbol 'bad_wr'
'bad_wr' is initialized in ib_post_send. But smatch
doesn't know that and warns this.
