Make it use the correct API, but since this may already be used as-is by userspace, reserve a family ID for this code and also reserve that group ID to not break userspace assumptions. My previous patch broke event delivery in the driver as I missed that it wasn't using the right API and forgot to update it later in my series. While changing this, I noticed that the genetlink code could use the static group ID instead of a strcmp(), so also do that for the VFS_DQUOT family. Cc: Anil Ravindranath Cc: "James E.J.
