+ * Lustre wire protocol definitions.
+ *
+ * All structs passing over the wire should be declared here (lov_mds_md
+ * being the lone exception). Structs must be properly aligned to put
+ * 64-bit values on an 8-byte boundary. Any structs being added here
+ * must also be added to utils/wirecheck.c and "make newwiretest" run
+ * to regenerate the utils/wiretest.c sources. This allows us to verify
+ * that wire structs have the proper alignment/size on all architectures.
+ *
+ * We assume all nodes are either little-endian or big-endian, and we
+ * always send messages in the sender's native format. The receiver
+ * detects the message format by checking the 'magic' field of the message
+ * (see lustre_msg_swabbed() below).
+ *
+ * Each wire type has corresponding 'lustre_swab_xxxtypexxx()' routines,
+ * implemented either here, inline (trivial implementations) or in
+ * ptlrpc/pack_generic.c. These 'swabbers' convert the type from "other"
+ * endian, in-place in the message buffer.
+ *
+ * A swabber takes a single pointer argument. The caller must already have
+ * verified that the length of the message buffer >= sizeof (type).
+ *
+ * For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine
+ * may be defined that swabs just the variable part, after the caller has
+ * verified that the message buffer is large enough.
