From b075dd40c95d11c2c8690f6c4d6232fc0d9e7f56 Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Tue, 18 Feb 2014 02:19:26 -0300 Subject: Bluetooth: allocate static minor for vhci Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI driver) added the module alias to hci_vhci module so it's possible to create the /dev/vhci node. However creating an alias without specifying the minor doesn't allow us to create the node ahead, triggerring module auto-load when it's first accessed. Starting with depmod from kmod 16 we started to warn if there's a devname alias without specifying the major and minor. Let's do the same done for uhid, kvm, fuse and others, specifying a fixed minor. In systems with systemd as the init the following will happen: on early boot systemd will call "kmod static-nodes" to read /lib/modules/$(uname -r)/modules.devname and then create the nodes. When first accessed these "dead" nodes will trigger the module loading.
