Use landlock_cred(file->f_cred)->domain instead of landlock_get_current_domain() in security_file_open() hook implementation. This should not change the current behavior but could avoid potential race conditions in case of current task's credentials change. This will also ensure consistency with upcoming audit support relying on file->f_cred. Add and use a new get_fs_domain() helper to mask non-filesystem domains. file->f_cred is set by path_openat()/alloc_empty_file()/init_file() just before calling security_file_alloc().

README
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.
