Subject: [PATCH 4/5] perf trace: Add -a switch for --all-cpus option
Date: Fri, 5 Oct 2012 14:02:15 +0900 [thread overview]
Message-ID: <1349413336-26936-4-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1349413336-26936-1-git-send-email-namhyung@kernel.org>
From: Namhyung Kim <namhyung.kim@lge.com>
Other perf subcommands like record, top and stat use '-a' as a
shortcut for --all-cpus option. Just follow the convention. :)
