Here I meant "how good to your problem" by the word "effective".
Note that your problem is about space instead of time.
- "trunc_xino" reduces the number of consumed blocks by XINO files. But
  it is not guranteed, and sometimes the number will be little.
- "ino" option for tmpfs ensures the lowest unused inum, and it makes
  aufs XINO files always smallest.
So the latter is "effective" to the "space" problem.

And I am still considering these two points.
- generality of the patch
  Because the patch is not for aufs, it can widely affect your
  system. Of course, "noino" is for that case.
- performance of the patch
  Because it depends upon a single lock, it can be a bottle-neck somtimes
  I am afraid.
