Always synchronize access_masked_parent* with access_request_parent* according to allowed_parent*. This is required for audit support to be able to get back to the reason of denial. In a rename/link action, instead of always checking a rule two times for the same parent directory of the source and the destination files, only check it when an action on a child was not already allowed. This also enables us to keep consistent allowed_parent* status, which is required to get back to the reason of denial. For internal mount points, only upgrade allowed_parent* to true but do not wrongfully set both of them to false otherwise. This is also required to get back to the reason of denial. This does not impact the current behavior but slightly optimize code and prepare for audit support that needs to know the exact reason why an access was denied.

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 reStructuredText 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.
