+ * These are above an upper limit so they do not collide with static minors.
+ * Furthermore, you can save an arbitrary data pointer with them so you don't
+ * have to keep a list of dynamic minors yourself.
+ *
+ * There can be up to INPUT_TABLE_SIZE static minor users with 32 minors for
+ * each. Therefore, we start allocating dynamic minors beyond
+ * INPUT_TABLE_SIZE << 5. But we still must make sure we are below INPUT_DEVICES
+ * which is the upper limit and maximum minor size that we allocate on startup.
