Subject: Bluetooth: allocate static minor for vhci
|
|
|
c1f2f5b |
|
|
|
c1f2f5b |
Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI
|
|
|
c1f2f5b |
driver) added the module alias to hci_vhci module so it's possible to
|
|
|
c1f2f5b |
create the /dev/vhci node. However creating an alias without
|
|
|
c1f2f5b |
specifying the minor doesn't allow us to create the node ahead,
|
|
|
c1f2f5b |
triggerring module auto-load when it's first accessed.
|
|
|
c1f2f5b |
|
|
|
c1f2f5b |
Starting with depmod from kmod 16 we started to warn if there's a
|
|
|
c1f2f5b |
devname alias without specifying the major and minor.
|
|
|
c1f2f5b |
|
|
|
c1f2f5b |
Let's do the same done for uhid, kvm, fuse and others, specifying a
|
|
|
c1f2f5b |
fixed minor. In systems with systemd as the init the following will
|
|
|
c1f2f5b |
happen: on early boot systemd will call "kmod static-nodes" to read
|
|
|
c1f2f5b |
/lib/modules/$(uname -r)/modules.devname and then create the nodes. When
|
|
|
c1f2f5b |
first accessed these "dead" nodes will trigger the module loading.
