* Structs must be properly aligned to put 64-bit values on an 8-byte

- * 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.
