The client has been setting up a reply chunk for NFS READs that are smaller than the inline threshold. This is not efficient: both the server and client CPUs have to copy the reply's data payload into and out of the memory region that is then transferred via RDMA. Using the write list, the data payload is moved by the device and no extra data copying is necessary. Signed-off-by: Chuck Lever <chuck.lever@xxxxxxxxxx>
