-'ptlrpc_body':: RPC descriptor. Only the 'pb_opc' value (OST_STATFS =
-41) is directly relevant to the OST_STATFS request message. The rest
-of the 'ptlrpc_body' fields handle generic information about the
-RPC, as discussed in <<struct-ptlrpc-body>>, including generic error
-conditions. In a normal reply ('pb_type' = PTL_RPC_MSG_REPLY) the
-'pb_status' field is 0.  The one error that can be returned in
-'pb_status' that is speficially from OST_STATFS' handling is -ENOMEM,
-which occurs if there is not enough memory to allocate a temporary
-buffer for the 'statfs' data.
