Phil Sutter e859afe1ee lib: test_rhashtable: fix for large entry counts
During concurrent access testing, threadfunc() concatenated thread ID
and object index to create a unique key like so:

| tdata->objs[i].value = (tdata->id << 16) | i;

This breaks if a user passes an entries parameter of 64k or higher,
since 'i' might use more than 16 bits then. Effectively, this will lead
to duplicate keys in the table.

Fix the problem by introducing a struct holding object and thread ID and
using that as key instead of a single integer type field.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
