From 1e33a8b408123a4e02a6b9135807f6fd61f3e235 Mon Sep 17 00:00:00 2001
From: Theodore Ts'o <tytso@mit.edu>
Date: Sat, 26 Jul 2014 07:40:36 -0400
Subject: [PATCH] Fix 32/64-bit overflow when multiplying by blocks/clusters
per group
References: bsc#1009532
There are a number of places where we need convert groups to blocks or
clusters by multiply the groups by blocks/clusters per group.
Unfortunately, both quantities are 32-bit, but the result needs to be
64-bit, and very often the cast to 64-bit gets lost.
Fix this by adding new macros, EXT2_GROUPS_TO_BLOCKS() and
EXT2_GROUPS_TO_CLUSTERS().
This should fix a bug where resizing a 64bit file system can result in
calculate_minimum_resize_size() looping forever.
