Android-R /sdcard mount FUSE filesystem type,
use "dd" command to filli up /sdcard dir,
Android will not boot normal,
becase this system need at least 128M userspace.

Test: open adb port,
      adb shell "dd if=dev/zero of=sdcard/ae bs=1024000 count=xxx"

Result: if not limit size,Android system  can not boot normal.

Without understanding the specifics, this does not look like a kernel
issue at all.

Why can't the fuse server do the limiting?

Upstream nevert do the limiting,This leads to the problems I mentioned above。
That's why I want to solve it from kernel.

Upstream of what?

Thanks,
