The number * encodes two values -- a boolean which indicates whether the fragment * is the last fragment of the record (bit value 1 implies the fragment * is the last fragment) and a 31-bit unsigned binary value which is the * length in bytes of the fragment's data. The boolean value is the * highest-order bit of the header; the length is the 31 low-order bits. * (Note that this record specification is NOT in XDR standard form!)" * * The Linux RPC client always sends its requests in a single record * fragment, limiting the maximum payload size for stream transports to * 2GB. */ typedef u32 rpc_fraghdr; #define RPC_LAST_STREAM_FRAGMENT (1U << 31) #define RPC_FRAGMENT_SIZE_MASK (~RPC_LAST_STREAM_FRAGMENT) #define RPC_MAX_FRAGMENT_SIZE ((1U << 31) - 1) #endif /* __KERNEL__ */ #endif /* _LINUX_SUNRPC_MSGPROT_H_ */
