返回类型：void

参数：

类型参数名称
const char *order
const char *origin
213  以lsm小于__end_lsm_info循环
214  如果 Optional: default is LSM_ORDER_MUTABLE 恒等于 This is only for capabilities. 则append_ordered_lsm(lsm, "first")
219  如果chosen_major_lsm则
228  以major小于__end_lsm_info循环
230  如果 Optional: flags describing LSM 按位与LSM_FLAG_LEGACY_MAJOR且字符串比较不等于0则
232  set_enabled(major, false)
233  init_debug("security=%s disabled: %s\n", chosen_major_lsm, Required. )
239  sep等于kstrdup - allocate space for and copy an existing string*@s: the string to duplicate*@gfp: the GFP mask used in the kmalloc() call when allocating memory* Return: newly allocated copy of @s or %NULL in case of error
240  next等于sep
242  当((name = 分割字符串) != NULL)循环
243  bool found = false
245  以lsm小于__end_lsm_info循环
246  如果 Optional: default is LSM_ORDER_MUTABLE 恒等于LSM_ORDER_MUTABLE且字符串比较恒等于0则
248  append_ordered_lsm(lsm, origin)
249  found = true
253  如果非found则init_debug("%s ignored: %s\n", origin, name)
258  如果chosen_major_lsm则
259  以lsm小于__end_lsm_info循环
260  如果Is an LSM already listed in the ordered LSMs list? 则继续下一循环
262  如果字符串比较恒等于0则append_ordered_lsm(lsm, "security=")
268  以lsm小于__end_lsm_info循环
269  如果Is an LSM already listed in the ordered LSMs list? 则继续下一循环
271  set_enabled(lsm, false)
