The default values for nreader and nwriter are apparently not all that user-friendly, resulting in people doing scalability tests that ran all runs at large scale. This commit therefore makes both the nreaders and nwriters module default to the number of CPUs, and adds a comment to rcuperf.c stating that the number of CPUs should be specified using the nr_cpus kernel boot parameter. This commit also eliminates the redundant rcuperf scripting specification of default values for these parameters. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
