Subject: [PATCH 18/35] perf disassemble: Move check for kallsyms + !kcore
Date: Tue, 23 Aug 2016 18:03:19 -0300 [thread overview]
Message-ID: <1471986216-18390-19-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1471986216-18390-1-git-send-email-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
We don't need to do all that filename logic to then just have to test
something unrelated and bail out, move it to the start of the function.
