Subject: [PATCH 1/6] 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.
