From 5173fbb8a11b2857aeec9e5f4e9568d4e1b84dbd Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 14 Jul 2014 13:02:38 +0300 Subject: perf buildid-cache: Apply force option to copying kcore Currently a copy of kcore is not made if there is one already with the same modules at the same addresses. Change this to make a copy anyway if the force (-f) option is also used.
