Subject: [PATCH 35/46] perf tools: Fix symbol and object code resolution for vdso32 and vdsox32
Date:   Tue,  5 Jun 2018 14:50:19 -0300
Message-Id: <20180605175030.32549-36-acme@kernel.org>
In-Reply-To: <20180605175030.32549-1-acme@kernel.org>
References: <20180605175030.32549-1-acme@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Adrian Hunter <adrian.hunter@intel.com>

Fix __kmod_path__parse() so that perf tools does not treat vdso32 and
vdsox32 as kernel modules and fail to find the object.
