Yes it is unwanted. This is some special pattern for vfio's unique needs. Since this has a struct device for each char dev instance please use the normal cdev_device_a...

[PATCH] vhost: introduce vDPA based backend
...r-vdpa char dev named vhost-vdpa/$vdpa_device_index in dev. I followed the code in VFIO which creates char dev vfio/$GROUP dynamically, e.g.: https://github.com/torvalds/linux/blob/b1da3acc781c/drivers/vfio/vfio.c#L2164-L2180 https://github.com/torvalds/linux/blob/b1da3acc781c/drivers/vfio/vfio.c#L373-L387 https://github.com/torvalds/linux/blob/b1da3acc781c/drivers/vfio/vfio.c#L1553 Is it something unwanted? Thanks for the review. Regards, Tiwei > > If so, why is there this: > > +static int vhost_vdpa_open(struct inode *inode, struct file *filep) > +{ > + struct vhost_vdp...
