Hash Suite for Android: free password hash cracker in your pocket
[<prev] [next>] [thread-next>] [day] [month] [year] [list]
Date:	Wed,  5 Nov 2008 00:30:55 -0500
From:	Theodore Ts'o <tytso@....edu>

Cc:	Theodore Ts'o <tytso@....edu>
Subject: [PATCH, RFC] ext4: Make ext4_group_t be an unsigned int

Nearly all places in the ext3/4 code which uses "unsigned long" is
probably a bug, since on 32-bit systems a ulong a 32-bits, which means
we are wasting stack space on 64-bit systems.
