Convert all completions to use the new completion routine that fixes a race between post send and completion where fields from a SWQE can be read after SWQE has been freed. This patch also addresses issues reported in https://marc.info/?l=linux-kernel&m=155656897409107&w=2. The reserved operation path has no need for any barrier. The barrier for the other path is addressed by the smp_load_acquire() barrier. Cc: Andrea Parri <andrea.parri@amarulasolutions.com> Reviewed-by: Michael J.

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.
