In 2.0, mem.c has this:

#define read_full read_null

In 2.1, it has been changed:

#define read_full read_zero

So, it looks like everybody is right. Depends on which kernel you run. :)

The lesson here, is to use /dev/zero when you mean it, and /dev/null
when you mean it, and don't use /dev/full for anything useful. :)
