31 * We assume all nodes are either little-endian or big-endian, and we
32 * always send messages in the sender's native format. The receiver
33 * detects the message format by checking the 'magic' field of the message
34 * (see lustre_msg_swabbed() below).
36 * Each type has corresponding 'lustre_swab_xxxtypexxx()' routines
37 * are implemented in ptlrpc/pack_generic.c. These 'swabbers' convert the
38 * type from "other" endian, in-place in the message buffer.
40 * A swabber takes a single pointer argument. The caller must already have
41 * verified that the length of the message buffer >= sizeof (type).
43 * For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine
44 * may be defined that swabs just the variable part, after the caller has
45 * verified that the message buffer is large enough.
