Currently, all binder state and statistics live in debugfs. We need this information even when debugfs is not mounted. This patch adds the mount option 'stats' to enable a binderfs instance to have binder debug information present in the same. 'stats=global' will enable the global binder statistics. In the future, 'stats=local' will enable binder statistics local to the binderfs instance. The two modes 'global' and 'local' will be mutually exclusive. 'stats=global' option is only available for a binderfs instance mounted in the initial user namespace. An attempt to use the option to mount a binderfs instance in another user namespace will return an EPERM error.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
