[ Upstream commit 76d3ddff7153cc0bcc14a63798d19f5d0693ea71 ] 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.

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.
