Yishai Hadas c411a3c828 RDMA/mlx5: Relax DEVX access upon modify commands
[ Upstream commit be551ee1574280ef8afbf7c271212ac3e38933ef ]

Relax DEVX access upon modify commands to be UVERBS_ACCESS_READ.

The kernel doesn't need to protect what firmware protects, or what
causes no damage to anyone but the user.

As firmware needs to protect itself from parallel access to the same
object, don't block parallel modify/query commands on the same object in
the kernel side.

This change will allow user space application to run parallel updates to
different entries in the same bulk object.

README

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.
