Jens Axboe b392402d29 io_uring/kbuf: protect io_buffer_list teardown with a reference
commit 6b69c4ab4f685327d9e10caf0d84217ba23a8c4b upstream.

No functional changes in this patch, just in preparation for being able
to keep the buffer list alive outside of the ctx->uring_lock.

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.
