Section 4 of RFC 5667 (NFS/RDMA) says: > The server MUST ignore any Read list for other NFS procedures, > as well as additional Read list entries beyond the first in the > list.
Our XDR code adds a zero pad at the end of NFS WRITEs and SYMLINKs whose content is not a multiple of 4 octets long. xprtrdma treats the tail buffer containing the zero pad as a separate read chunk, which the server ignores. Enable the pad optimization so our NFS client avoids sending zeroes the server is just going to ignore.
