Would be great if we could add that after rc1 is out. Would you have time to do that, Hridya? Should just be a new entry under: Options ------- max binderfs instances can be mounted with a limit on the number of binder devices that can be allocated. The ``max=<count>`` mount option serves as a per-instance limit. If ``max=<count>`` is set then only ``<count>`` number of binder devices can be allocated in this binderfs instance. stats <description> Thanks!
