1 lustre/ptlrpc/layout.c establishes a mapping between the symbols
2 (starting with RMF_) for message format structures and the actual
3 structure definitions they represent. There are three entries in this
4 mapping that do not appear in any message format. They are:
8 There are also three duplicates:
11 RMF_FIEMAP_KEY => fiemap and
12 RMF_FIEMAP_VAL => fiemap
13 RMF_NIOBUF_REMOTE => niobuf_remote and
14 RMF_RCS => niobuf_remote
16 The mesage format symbols RMF_MGS_CONFIG_BODY and RMF_MGS_CONFIG_RES
17 have the names, respecitvely, "mgs_config_read request" and
18 "mgs_config_read reply" with two words (or a missing
19 underscore). Similarly, RMF_U32 has the name "generic u32".
21 Many of the message format symbols have a name that is the same as the
22 symbol but in lower case and with out the leading "RMF_". On the other
23 hand many of the symbols do not follow this pattern. Each declaration
24 also has a field for the size to be allocated for the structure, and
25 most use the "sizeof(struct the_struct)" construction to identify the
26 size needed. That construct then gives a notion of what actual
27 structure definition is going to give meaning to the bytes in that
28 structure. The sizeof column presents that 'struct' name or a hint
29 about the size of the message. A value of "-1" means, "the size is not
30 going to be well defined in advance." Thus additional hits will need
31 ot be included in the rest of the message.
