Earlier patches added memory barriers to protect user space to kernel space communications. The user space queues were previously shown to have occasional memory synchonization errors which were removed by adding smp_load_acquire, smp_store_release barriers. This patch extends that to the case where queues are used between kernel space threads. This patch also extends the queue types to include kernel ULP queues which access the other end of the queues in kernel verbs calls like poll_cq and post_send/recv.

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.
