This update splits old MTP code and new MTP code from Google into two trees, legacy and ffs. Depending on the SDK level, the build system will select the correct version. The reason for separating the versions out are due to older android trees not supporting the updated MTP code from Google. Most MTP code is from Google, with additions needed from implementing the Java functions in C++ for TWRP and FFS. We assume if you are in android-9.0 or above, your kernel has support for FFS over MTP. Verify that your init.rc is mounting the MTP FFS driver to the proper location.
