From e7fa68ba61691d21444df28ba7b6eb91517c99da Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 12 Sep 2013 18:39:36 +0200 Subject: [PATCH] perf kmem: Make it work again on non NUMA machines commit 4921e320244e099bdf237fd10428594ce5f5b87d upstream. The commit '2814eb0 perf kmem: Remove die() calls' disabled 'perf kmem' command for machines without numa support. It made the command fail if '/sys/devices/system/node' dir wasn't found. Skipping the numa based initialization in case the directory is not found and continue execution.
