file system - Why does Android use fuse for internal SD card mount?



The android ICS or later version(JB) use /data/media directory for internal SD card, and use fuse for mounting the emulator internal sd card device (/dev/fuse).


As we know if we use fuse, the files access have to communicate with userspace with low effect, why android do not use a stackable passthru filesystem such as wrapfs(wrapfs.filesystems.org) to mount the /data/media direct to internal sd card path(/storage/scard0)?


Especially, we have the MTP option access internal sdcard and external sdcard for PC(windows)
