From c16831b4cc9b0805adf8ca3001752a7ec10a17bf Mon Sep 17 00:00:00 2001 From: Manish Katiyar Date: Thu, 12 Feb 2009 21:57:04 +0100 Subject: ext2: Zero our b_size in ext2_quota_read() ext2_quota_read() doesn't initialize tmp_bh.b_size before calling ext2_get_block() where we access it. Since it is a local variable it might contain some garbage. Make sure it is filled with reasonable value before passing.
