The Ext2/Ext3/Ext4 Filesystems: ext4 Filesystem Features section has a few typos. "Increases the maximum filesytem size to 1 EB (from 16 TB), and the maximum file to 16 TB (from 2 TB)."
Should be filesystems, EiB, and TiB.
Thanks, you are write. The TiB vs TB etc issue is something that is often sloppily addressed, but in this kind of context not important. On the other hand, I suspect there are plenty of people who are used to MB not MiB etc.
