From 3aa5939d71fa22a947808ba9c798b8537c35097a Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 15 Nov 2013 15:52:29 +0200 Subject: perf record: Make per-cpu mmaps the default. This affects the -p, -t and -u options that previously defaulted to per-thread mmaps. Consequently add an option to select per-thread mmaps to support the old behaviour. Note that per-thread can be used with a workload-only (i.e. none of -p, -t, -u, -a or -C is selected) to get a per-thread mmap with no inheritance.
