Patch series "signal: refactor some functions", v3. This series refactors a bunch of functions in signal.c to simplify parts of the code. The greatest single change is declaring the static do_sigpending() helper as void which makes it possible to remove a bunch of unnecessary checks in the syscalls later on. This patch (of 17): force_sigsegv() returned 0 unconditionally so it doesn't make sense to have it return at all. In addition, there are no callers that check force_sigsegv()'s return value.

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.
