   the script used for generating test inputs:
   
       declare -A sizes=(
   	[1024,1024]=$((130048 + 1024))
   	[2048,512]=$((  45056 + 2048))
   	[4096,128]=$((  53248 + 4096))
       )
   
       adjust_size()
       {
   	local f=$1
   	local bsize=$2
   	local isize=$3
   
   	truncate --size=${sizes[$bsize,$isize]} $f
       }
   
       makeimg()
       {
   	local bsize=$1
   	local isize=$2
   
   	local f=tests/files/bsize-${bsize}-isize-${isize}.ext2
   	dd if=/dev/zero of=$f bs=${bsize} count=128
   	mkfs.ext2 -I ${isize} -b ${bsize} $f
   	sudo mount $f __tmp__
   	echo hello | sudo dd if=/dev/stdin of=__tmp__/source
   	(cd __tmp__/; sudo ln -s source target)
   	sudo umount __tmp__
   	adjust_size $f $bsize $isize
       }
