Joanne Koong 95c39eef7c fuse: fix io-uring list corruption for terminated non-committed requests
When a request is terminated before it has been committed, the request
is not removed from the queue's list. This leaves a dangling list entry
that leads to list corruption and use-after-free issues.

Remove the request from the queue's list for terminated non-committed
requests.

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 reStructuredText 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.
