Android 编译问题，求个大佬进来看看。

最近编译源码 Android9.0
在 mk 里面遇到一个奇怪的注释：

IoStats are parcelable types (vs. interface types), but the build system uses an initial I as a magic marker to mean "interface", and due to this ends up refusing to compile these files as part of the build process.
A clean solution to this is actively being worked on by the build team, but is not yet available, so for now we just filter the files out by hand.*

car_lib_sources := $(filter-out src/android/car/storagemonitoring/IoStats.aidl,$(car_lib_sources)) car_lib_sources := $(filter-out src/android/car/storagemonitoring/IoStatsEntry.aidl,$(car_lib_sources))

public final class IoStatsEntry implements Parcelable {
...省略代码
}
public class IoStats implements Parcelable {
...省略代码
}

为什么在编译的时候，把这两个I开头的 aidl 文件过滤掉？这个是系统的规则嘛？
