Subject: perf bench: Set more defaults in the 'numa' suite
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=40ba93e3aa001246110320edbe8cf2eb488c1fe7;p=linux.git

perf bench: Set more defaults in the 'numa' suite

Currently,

  $ perf bench numa mem

errors out with usage information. To make this more user-friendly, let
us provide a minimum set of default values required for a test
run. As an added bonus,

  $ perf bench all

now goes all the way to completion.
