[PATCH 2/2] perf tools: Fix symbol and object code resolution for vdso32 and vdsox32

From: Adrian Hunter
Date: Mon Jun 04 2018 - 08:58:26 EST


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

Fixes: 1f121b03d058 ("perf tools: Deal with kernel module names in '[]' correctly")
