Subject: [GIT PATCH 04/18] mousedev: fix memory leak
Date: Tue, 31 Jan 2006 23:55:18 -0500 [thread overview]
Message-ID: <20060201050733.733781000.dtor_core@ameritech.net> (raw)
In-Reply-To: 20060201045514.178498000.dtor_core@ameritech.net
[-- Attachment #1: mousedev-fix-leak.patch --]
[-- Type: text/plain, Size: 1389 bytes --]
From: Kimball Murray <kimball.murray@stratus.com>
Input: mousedev - fix memory leak
Apparently, "while true; do cat </dev/null >/dev/input/mice; done" causes
an OOM in a short amount of time. Funny that nobody noticed, it actually
is very easy to trigger just by switching between VT1 and VT7...
