Since tomoyo_memory_ok() will check for null pointer returned by kzalloc() in tomoyo_assign_profile(), tomoyo_assign_namespace(), tomoyo_get_name() and tomoyo_commit_ok(), then emit OOM warnings if needed. And this is the expected behavior as informed by Tetsuo Handa. Let's add __GFP_NOWARN to kzalloc() in those related functions. Besides, to achieve this goal, remove the null check for entry right after kzalloc() in tomoyo_assign_namespace().

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.
