From f885037ef6400ce4a4c122a88845dea2c9bca256 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 28 Nov 2013 17:57:22 +0100 Subject: [PATCH] perf trace: Honour -m option Currently trace command supports '-m' option, but does not honours its value and keeps the default. Changing the perf_evlist__mmap function call to use the '-m' configured value.
