5 The 'ost_body' structure just holds a 'struct 'obdo', which is where
6 all the actual information is conveyed.
19 The 'obdo' structure conveys metadata about a resource on an OST.
25 struct ost_id o_oi; /* OBD_MD_FLID */

55 The 'o_valid' field identifies which other fields in the structure are
56 to be interpreted. The flags are the same set (with additions) used
57 for the 'mdt_body' field 'mbo_valid' (see <<struct-mdt-body>>).

116 The two fields here that are specific to the 'ost_body' case are the
117 'o_oi' and the 'o_stripe_idx', which give the identity of the OST and
118 the stripe index assigned to it.
