函数原型：static int ima_eventname_init_common(struct ima_event_data *event_data, struct ima_field_data *field_data, bool size_limit)

返回类型：int

参数：

类型参数名称
struct ima_event_data *event_data
struct ima_field_data *field_data
boolsize_limit
371  const char * cur_filename = NULL
372  cur_filename_len等于0
374  BUG_ON(filename == NULL && file == NULL)
376  如果filename则
377  cur_filename等于filename
378  cur_filename_len等于strlen - Find the length of a string*@s: The string to be sized
380  如果非size_limit或cur_filename_len小于等于IMA_EVENT_NAME_LEN_MAX则转到:out
384  如果file则
385  cur_filename等于name
386  cur_filename_len等于strlen - Find the length of a string*@s: The string to be sized
387  否则cur_filename_len等于IMA_EVENT_NAME_LEN_MAX
393  out :
394  返回:ima_write_template_field_data(cur_filename, cur_filename_len, DATA_FMT_STRING, field_data)
