Provide userspace with a mechanism to discover features supported by the binder driver to refrain from using any unsupported ones in the first place. Starting with "oneway_spam_detection" only new features are to be listed under binderfs and all previous ones are assumed to be supported. Assuming an instance of binderfs has been mounted at /dev/binderfs, binder feature files can be found under /dev/binderfs/features/. Usage example: $ mkdir /dev/binderfs $ mount -t binder binder /dev/binderfs $ cat /dev/binderfs/features/oneway_spam_detection 1 Acked-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: Carlos Llamas <cmllamas@google.com> Link: https://lore.kernel.org/r/20210715031805.1725878-1-cmllamas@google.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
