This advice is not applicable for ext4, since it will not read unused
portions of the inode table. There have been a number of improvements
in the ext4 file system format which means that in general fsck times
for ext4 are around 7-12 times faster than the equivalent ext3 file
system.

I've never heard of "mke4fs" --- who thought up that abortion?
"mke2fs -t ext4" and "mkfs.ext4" will both do the right thing, as far
as creating file systems that have the correct ext4 file system
features for a file system designed to be mounted using the ext4 file
system driver in modern Linux kernels.
