| * 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 |
| * are implemented in ptlrpc/lustre_swab.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. |
