Documentation wrong? "The number of block groups is the size of the device divided by the size of a block group."

[Serdar Sanli <mserdarsanli@xxxxxxxxx>]

Hi,

In the ext4 documentation here https://www.kernel.org/doc/html/latest/filesystems/ext4/overview.html it says:

> The number of block groups is the size of the device divided by the size of a block group.

Though when the device size is not a multiple of block group size, there is another group for the remaining part?

Can someone please clarify?

Thanks.
