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
