Subject: [PATCH 2/6] trace: add gcc printf check to trace_seq_printf
Date: Thu, 15 Jan 2009 23:53:44 -0500	[thread overview]
Message-ID: <20090116045417.820150410@goodmis.org> (raw)
In-Reply-To: 20090116045342.748642160@goodmis.org

[-- Attachment #1: 0002-trace-add-gcc-printf-check-to-trace_seq_printf.patch --]
[-- Type: text/plain, Size: 875 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Andrew Morton suggested adding a printf checker to trace_seq_printf
since there are a number of users that have improper format arguments.
