参数：

类型参数名称
struct audit_features *uaf
1107  BUILD_BUG_ON - break compile if a condition is true(AUDIT_LAST_FEATURE + 1 > ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(audit_feature_names))
1111  以i小于等于AUDIT_LAST_FEATURE循环
1112  feature等于mask for __u32 (i)
1116  如果非feature按位与 which bits we are dealing with 的值则继续下一循环
1119  old_feature等于 which feature to enable/disable 按位与feature
1120  new_feature等于 which feature to enable/disable 按位与feature
1121  new_lock等于 which features to lock 按位或 which features to lock 的值按位与feature
1122  old_lock等于 which features to lock 按位与feature
1125  如果old_lock且new_feature不等于old_feature则
1126  audit_log_feature_change(i, old_feature, new_feature, old_lock, new_lock, 0)
1128  返回:负EPERM
1132  以i小于等于AUDIT_LAST_FEATURE循环
1133  feature等于mask for __u32 (i)
1137  如果非feature按位与 which bits we are dealing with 的值则继续下一循环
1140  old_feature等于 which feature to enable/disable 按位与feature
1141  new_feature等于 which feature to enable/disable 按位与feature
1142  old_lock等于 which features to lock 按位与feature
1143  new_lock等于 which features to lock 按位或 which features to lock 的值按位与feature
1145  如果new_feature不等于old_feature则audit_log_feature_change(i, old_feature, new_feature, old_lock, new_lock, 1)
1149  如果new_feature则 which feature to enable/disable 或等于feature
1151  否则 which feature to enable/disable 与等于feature的反
1153  which features to lock 或等于new_lock
1156  返回:0
