From: Andi Kleen Date: Thu, 31 Jul 2014 06:45:04 +0000 (+0800) Subject: perf record: Honour --no-time command line option X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8affc2b8c27bfc2d6e70827b746f490b62c44eaa;p=openwrt%2Fstaging%2Fblogic.git perf record: Honour --no-time command line option Time stamps are always implicitely enabled for record currently. The old --time/-T option is a nop. Allow the user to disable timestamps by using --no-time, honouring the existing option. The defaults are unchanged.
