In kernel benchmarks are benchmarks that directly run in kernel space.

The test modules are regular kernel modules that can be loaded with

	modprobe slab_test

or so. 

The initialization function of the module will then run the test
and fail so that the module is not loaded. The output of the test
results will be written to the system log.

This is a rough draft. I have used these in the past to benchmark
page allocator, slab allocator and vmstat performance.
