From c353c3fb0700a3c17ea2b0237710a184232ccd7f Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Fri, 2 Feb 2007 16:39:12 +0100 Subject: Driver core: let request_module() send a /sys/modules/kmod/-uevent On recent systems, calls to /sbin/modprobe are handled by udev depending on the kind of device the kernel has discovered. This patch creates an uevent for the kernels internal request_module(), to let udev take control over the request, instead of forking the binary directly by the kernel. The direct execution of /sbin/modprobe can be disabled by setting: /sys/module/kmod/mod_request_helper (/proc/sys/kernel/modprobe) to an empty string, the same way /proc/sys/kernel/hotplug is disabled on an udev system.
