From: Kristian Hunt Date: Thu, 17 Dec 2015 11:15:32 +0000 (+0100) Subject: Fix lmbench memory read latency stop size X-Git-Tag: brahmaputra.1.0~115 X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=804abc1206a1ca23d1d1eca0b63b54abca850a26;p=yardstick.git Fix lmbench memory read latency stop size Stop size parameter's type should be float to allow for performing measurements on only L1 and L2 cache if needed.
