Currently, lock_torture_cleanup() uses the values of cxt.lwsa and cxt.lrsa to detect bad parameters that prevented locktorture from initializing, let alone running. In this case, lock_torture_cleanup() does no cleanup aside from invoking torture_cleanup_begin() and torture_cleanup_end(), as required to permit future torture tests to run. However, this heuristic fails if the run with bad parameters was preceded by a previous run that actually ran: In this case, both cxt.lwsa and cxt.lrsa will remain non-zero, which means that the current lock_torture_cleanup() invocation will be unable to detect the fact that it should skip cleanup, which can result in charming outcomes such as double frees. This commit therefore NULLs out both cxt.lwsa and cxt.lrsa at the end of any run that actually ran. Signed-off-by: Paul E.

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.
