Selvin Xavier 730dc0818f RDMA/bnxt_re: synchronize the qp-handle table array 
[ Upstream commit 76d3ddff71 ]

There is a race between the CREQ tasklet and destroy qp when accessing the
qp-handle table. There is a chance of reading a valid qp-handle in the
CREQ tasklet handler while the QP is already moving ahead with the
destruction.

Fixing this race by implementing a table-lock to synchronize the access.

Fixes: f218d67ef0 ("RDMA/bnxt_re: Allow posting when QPs are in error")
Fixes: 84cf229f40 ("RDMA/bnxt_re: Fix the qp table indexing")

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.
