From 29c158e81c733ac7d6a75c5ee929f34fb9f92983 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 23 Aug 2011 13:20:46 +0200 Subject: [PATCH] nohz: Remove "Switched to NOHz mode" debugging messages When performing cpu hotplug tests the kernel printk log buffer gets flooded with pointless "Switched to NOHz mode..." messages. Especially when afterwards analyzing a dump this might have removed more interesting stuff out of the buffer. Assuming that switching to NOHz mode simply works just remove the printk.
