svcrdma: Update synopsis of svc_rdma_send_reply_msg() (db9602e4) · Commits · 戴 / test

Preparing for subsequent patches, no behavior change expected. Pass the RPC Call's svc_rdma_recv_ctxt deeper into the sendto() path. This enables passing more information about Requester- provided Write and Reply chunks into those lower-level functions. Signed-off-by:
