Subject: perf record: Make per-cpu mmaps the default.
X-Git-Tag: v3.14-rc1~171^2~19^2~22
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3aa5939d71fa22a947808ba9c798b8537c35097a;p=pandora-kernel.git

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.
