Subject: [PATCH] perf tools: Make trace command to follow -m option
Date: Thu, 28 Nov 2013 17:57:22 +0100	[thread overview]
Message-ID: <1385657842-8914-1-git-send-email-jolsa@redhat.com> (raw)

Currently trace command supports '-m' option, but
does not follow its value and keeps the default.

Changing the perf_evlist__mmap function call to use
the '-m' configured value.
