Make the code more robust by marking the point of no return sooner. This ensures that future code changes don't need to worry about how they return errors if they are past this point. This results in no actual change in behavior as __do_execve_file does not force SIGSEGV when there is a pending fatal signal pending past the point of no return. Further the only error returns from de_thread and exec_mmap that can occur result in fatal signals being pending.

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.
