To simplify the code, pull in checking the fatal signals into ep_send_events(). ep_send_events() is called only from ep_poll(). Note that, previously, we were always checking fatal events, but it is checked only if eavail is true. This should be fine because the goal of that check is to quickly return from epoll_wait() when there is a pending fatal signal.

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.
