The only output from this function is "clean log" or "dirty log".

so:

_scratch_xfs_logstate()
{
	_scratch_xfs_logprint -t | tee -a $seqres.full | grep -q "<CLEAN>"
	echo $?
}

_scratch_f2fs_logstate()
{
	$DUMP_F2FS_PROG $SCRATCH_DEV | tee -a $seqres.full | grep -q "unmount"
	echo $?
}

_print_logstate()
{
	case "$FSTYP" in
	xfs)
		dirty=$(_scratch_xfs_logstate)
		;;
	f2fs)
		dirty=$(_scratch_f2fs_logstate)
		;;
	*)
		;;
	esac

	if [ $dirty -ne 0 ]; then
		echo "dirty log"
	else
		echo "clean log"
	fi
}

Not sure why this is necessary, but I'll point that out where it is
used.

Actually, I'd make that

_require_logstate()
{
	case "$FSTYP" in
	xfs)
		if [ -z "$XFS_LOGPRINT_PROG" ]; then
			_notrun "This test requires xfs_logprint utility."
		fi
	f2fs)
		if [ -z "$DUMP_F2FS_PROG" ]; then
			_notrun "This test requires dump.f2fs utility."
		fi
		;;
	*)
		_notrun "$FSTYP does not support log state probing."
		;;
	esac
}
