Subject: [PATCH 05/15] perf jit: Move clockid validation
Date: Mon, 7 Mar 2016 16:44:41 -0300 [thread overview]
Message-ID: <1457379891-28516-6-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1457379891-28516-1-git-send-email-acme@kernel.org>
From: Adrian Hunter <ajhunter@gmail.com>
Move clockid validation into jit_process() so it can later be made
conditional.
