To allow the lock and unlock functions in locktorture to access per-thread information, we need to pass some hint on how to locate those information. One way to do this is to pass in a unique thread id which can then be used to access a global array for thread specific information. Change the lock and unlock method to add a thread id parameter which can be determined by the offset of the lwsp/lrsp pointer from the global lwsa/lrsa array. There is no other functional change in this patch.

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.
