Subject: [PATCH 01/13] perf timechart: Fix off-by-one error in 'record' argv handling
Date: Tue, 18 Mar 2014 18:25:53 -0300	[thread overview]
Message-ID: <1395177965-8879-2-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1395177965-8879-1-git-send-email-acme@infradead.org>

From: Ramkumar Ramachandra <artagnon@gmail.com>

Since 367b315 (perf timechart: Add support for -P and -T in timechart
recording, 2013-11-01), the 'perf timechart record' command stopped
working:

  $ perf timechart record -- git status
  Workload failed: No such file or directory

This happens because of an off-by-one error while preparing the argv for
cmd_record(): it attempts to execute the command 'status' and complains
that it doesn't exist. Fix this error.
