First, io_close() misses filp_close() and io_cqring_add_event(), when f_op->flush is defined. That's because in this case it will io_queue_async_work() itself not grabbing files, so the corresponding chunk in io_close_finish() won't be executed. Second, when submitted through io_wq_submit_work(), it will do filp_close() and *_add_event() twice: first inline in io_close(), and the second one in call to io_close_finish() from io_close(). The second one will also fire, because it was submitted async through generic path, and so have grabbed files. And the last nice thing is to remove this weird pilgrimage with checking work/old_work and casting it to nxt. Just use a helper instead.

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.
