| |
dynamic array is also added to struct ftrace_event_call->fields.
FTRACE_ENTRY(bprint) and FTRACE_ENTRY(print) use this __dynamic_array().
Preparing patch for new way of printing format files which uses defined fields to print formats. So it requires all fields are added to struct ftrace_event_call->fields.
