This should really use "run_e2fsck" to execute the test, instead of copying
a good chunk of that functionality here.  That will also make it more
consistent with the other tests.

It looks like you would need to set:

ONE_PASS_ONLY=true
FSCK_OPT="-n -b 8193 -fy"
PREP_CMD="$E2IMAGE_EXE -r -b 8193 -B 1024 $TMPFILE $TMPFILE.raw; \
	  mv $TMPFILE.raw $TMPFILE"
