Subject: [PATCH 19/29] perf report: Use parse_options_usage() for -s option failure
Date: Mon,  4 Nov 2013 14:58:57 -0300	[thread overview]
Message-ID: <1383587947-17419-20-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1383587947-17419-1-git-send-email-acme@infradead.org>

From: Namhyung Kim <namhyung.kim@lge.com>

The -s (--sort) option was processed after normal option parsing so that
it cannot call the parse_options_usage() automatically.  Currently it
calls usage_with_options() which shows entire help messages for event
option.  Fix it by showing just -s options.

  $ perf report -s help
    Error: Unknown --sort key: `help'

   usage: perf report [<options>]

      -s, --sort <key[,key2...]>
                            sort by key(s): pid, comm, dso, symbol, ...
