NeilBrown c6b0a9f87b [PATCH] knfsd: tidy up up meaning of 'buffer size' in nfsd/sunrpc ... There is some confusion about the meaning of 'bufsz' for a sunrpc server. In some cases it is the largest message that can be sent or received. In other cases it is the largest 'payload' that can be included in a NFS message. In either case, it is not possible for both the request and the reply to be this large. One of the request or reply may only be one page long, which fits nicely with NFS. So we remove 'bufsz' and replace it with two numbers: 'max_payload' and 'max_mesg'. Max_payload is the size that the server requests. It is used by the server to check the max size allowed on a particular connection: depending on the protocol a lower limit might be used. max_mesg is the largest single message that can be sent or received. It is calculated as the max_payload, rounded up to a multiple of PAGE_SIZE, and with PAGE_SIZE added to overhead. Only one of the request and reply may be this size. The other must be at most one page. Cc: Greg Banks <gnb@sgi.com> Cc: "J.
