Subject: [PATCH 15/24] perf thread_map: Create dummy constructor out of open coded equivalent
Date: Tue, 14 Oct 2014 18:04:24 -0300 [thread overview]
Message-ID: <1413320673-5784-16-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1413320673-5784-1-git-send-email-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Create a dummy thread_map, one that has just one entry and it is -1,
meaning 'all threads', as this ends up going down to perf_event_open().
