Subject: [PATCH 07/16] perf symbol: symplify out_fixup in kernel syms loading
Date: Thu, 9 Aug 2012 15:18:32 -0700 [thread overview]
Message-ID: <1344550721-21024-8-git-send-email-cody@linux.vnet.ibm.com> (raw)
In-Reply-To: <1344550721-21024-1-git-send-email-cody@linux.vnet.ibm.com>
The only site that jumps to out_fixup has (kallsyms_filename == NULL).
And all paths that reach 'if (err > 0)' without 'goto out_fixup' have
kallsyms_filename != NULL.
So skip over both the check & dso__set_long_name(), and remove the
check.
