I'm sitting in a talk from Jonathan about kernel documentation and what I realized is that we forgot to update the documentation I wrote for binderfs in Documentation/admin-guide/binderfs.rst to reflect the new stats=global mount option. 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! Christian
