This cosmetic change is needed for audit support, specifically to be able to filter according to cross-execution boundaries. Add landlock_get_applicable_subject(), mainly a copy of landlock_get_applicable_domain(), which will fully replace it in a following commit. Optimize current_check_access_path() to only handle the access request. Partially replace get_current_fs_domain() with explicit calls to landlock_get_applicable_subject(). The remaining ones will follow with more changes. Remove explicit domain->num_layers check which is now part of the landlock_get_applicable_subject() call.

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.
