The special overflow event is allocated as struct fanotify_path_event, but with a null path. Use a special event type to identify the overflow event, so the helper fanotify_has_event_path() will always indicate a non null path. Allocating the overflow event doesn't need any of the fancy stuff in fanotify_alloc_event(), so create a simplified helper for allocating the overflow event. There is also no need to store and report the pid with an overflow event.

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.
