    Push lock_super() into the ->remount_fs() of filesystems that care about it · bbd6851a

    Note that since we can't run into contention between remount_fs and write_super
    (due to exclusion on s_umount), we have to care only about filesystems that
    touch lock_super() on their own.  Out of those ext3, ext4, hpfs, sysv and ufs
    do need it; fat doesn't since its ->remount_fs() only accesses assign-once
    data (basically, it's "we have no atime on directories and only have atime on
    files for vfat; force nodiratime and possibly noatime into *flags").
