Subject: [PATCH 01/17] tracing/uprobes: Fix documentation of uprobe registration syntax
Date: Mon,  9 Dec 2013 15:19:49 +0900	[thread overview]
Message-ID: <1386570005-3368-2-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1386570005-3368-1-git-send-email-namhyung@kernel.org>

From: Namhyung Kim <namhyung.kim@lge.com>

The uprobe syntax requires an offset after a file path not a symbol.
