There will be another error type in COLO, which indicates a failover, that needs to be handled in restore(), so I moved the error handling down to avoid duplex code...Otherwise, in process_record, RECORD_NOT_PROCESSED is handled, and in restore another error type returned from process_record is handled... ~Andrew- else - { - ERROR("Mandatory record %#x (%s) not handled", - rec->type, rec_type_to_str(rec->type)); - rc = -1; - } - } - return rc; } @@ -678,7 +665,20 @@ static int restore(struct xc_sr_context *ctx) else { rc = process_record(ctx, &rec); - if ( rc ) + if ( rc == RECORD_NOT_PROCESSED ) + { + if ( rec.type & REC_TYPE_OPTIONAL ) + DPRINTF("Ignoring optional record %#x (%s)", + rec.type, rec_type_to_str(rec.type)); + else + { + ERROR("Mandatory record %#x (%s) not handled", + rec.type, rec_type_to_str(rec.type)); + rc = -1; + goto err; + } + } + else if ( rc ) goto err; }. -- Thanks, Yang. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
