[arch-releng] [PATCH 1/1] mkfs: limit size of ext4 block group descriptor table

[Christian Hesse]

From: Christian Hesse <mail at eworm.de>

The ext4 filesystems are create with a fixed size of 32GB. After mkfs
the empty filesystem already has a disk usage of about 4.3MB.
Limiting the size of ext4 block group descriptor table reduces this
to just 312KB.
