This cosmetic change is needed for audit support, specifically to be able to filter according to cross-execution boundaries. struct landlock_file_security's size stay the same for now but it will increase with struct landlock_cred_security's size. Only save Landlock domain in hook_file_set_fowner() if the current domain has LANDLOCK_SCOPE_SIGNAL, which was previously done for each hook_file_send_sigiotask() calls. This should improve a bit performance. Replace hardcoded LANDLOCK_SCOPE_SIGNAL with the signal_scope.scope variable. Use scoped guards for RCU read-side critical sections.

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.
