Subject: [patch 07/10] zfcp: Prevent access on uninitialized memory.
Date: Fri, 16 Jul 2010 15:37:40 +0200 [thread overview]
Message-ID: <20100716134300.705808000@de.ibm.com> (raw)
In-Reply-To: 20100716133733.621672000@de.ibm.com
[-- Attachment #1: 716-zfcp-kzalloc.diff --]
[-- Type: text/plain, Size: 899 bytes --]
From: Swen Schillig <swen@vnet.ibm.com>
Initialize allocated memory to zero to prevent access on error. This
prevents a possible error in the error handling path.
