Al Viro made some suggestions to improve the implementation of commit 0633da4 ("fix autofs_sbi() does not check super block type"). The check is unnecessary in all cases except for ioctl usage so placing the check in the super block accessor function adds a small overhead to the common case where it isn't needed. So it's sufficient to do this in the ioctl code only. Also the check in the ioctl code is needlessly complex.
