From 05e2e35715d104e9dd67b4013d9b16a47b8eb3c0 Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Fri, 7 Feb 2014 09:20:59 +0100 Subject: [PATCH] linux: don't automatically set uevent_helper with mdev /dev management MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When mdev /dev management is chosen in the buildroot configuration, the Linux configuration is updated automatically to set option CONFIG_UEVENT_HELPER_PATH to "/sbin/mdev". However, the help text of this option explicitly recommends not setting this option due to large performance impact during boot (experienced first hand by the reporter ánd author). The mdev startup script S10mdev already sets the helper during userspace boot, which will make sure mdev is working correctly.
