From fd2d42912f9f09e5250cb3b024ee0625704e9cb7 Mon Sep 17 00:00:00 2001 From: Avantika Mathur Date: Mon, 28 Jan 2008 23:58:27 -0500 Subject: ext4: add ext4_group_t, and change all group variables to this type. In many places variables for block group are of type int, which limits the maximum number of block groups to 2^31. Each block group can have up to 2^15 blocks, with a 4K block size, and the max filesystem size is limited to 2^31 * (2^15 * 2^12) = 2^58 -- or 256 PB This patch introduces a new type ext4_group_t, of type unsigned long, to represent block group numbers in ext4. All occurrences of block group variables are converted to type ext4_group_t.
