- make binderfs control dentry immutable:
We don't allow to unlink it since it is crucial for binderfs to be
useable but if we allow to rename it we make the unlink trivial to
bypass. So prevent renaming too and simply treat the control dentry as
immutable.
- add is_binderfs_control_device() helper:
Take the opportunity and turn the check for the control dentry into a
separate helper is_binderfs_control_device() since it's now used in two
places.
- simplify binderfs_rename():
Instead of hand-rolling our custom version of simple_rename() just dumb
the whole function down to first check whether we're trying to rename the
control dentry. If we do EPERM the caller and if not call simple_rename().

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
