    Subject[PATCH 01/10] perf/scripts: Fix supported language listing option
    Date
    From: Tom Zanussi <tzanussi@gmail.com>

    'perf trace -s list' prints a list of the supported scripting
    languages. One problem with it is that it falls through and prints
    the trace as well. The use of 'list' for this also makes it easy to
    confuse with 'perf trace -l', used for listing available scripts. So
    change 'perf trace -s list' to 'perf trace -s lang' and fixes the
    fall-through problem.
