Subject: Re: [PATCH v2] Bluetooth: allocate static minor for vhci

Hi Lucas,

> 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.

looks fine to me. If Kay and/or Greg want to ack it, then I take it through bluetooth-next tree.
