Patch "fs/aio: Make io_cancel() generate completions again" is based on the assumption that calling kiocb->ki_cancel() does not complete R/W requests. This is incorrect: the two drivers that call kiocb_set_cancel_fn() callers set a cancellation function that calls usb_ep_dequeue(). According to its documentation, usb_ep_dequeue() calls the completion routine with status -ECONNRESET. Hence this revert.

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.
