In practice this does not change anything as testing for fatal_signal_pending and exiting for with an error code duplicates the work of the next clause which recalculates pending signals and then exits fork if any are pending. In both cases the pending signal will trigger the slow path when existing to userspace, and the fatal signal will cause do_exit to be called. The advantage of making this a separate test is that it makes it clear processing the fatal signal will terminate the fork, and it allows the rest of the signal logic to be updated without fear that this important case will be lost.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
