[patch 0/3] lib: add synthetic MM benchmarks

[David Rientjes]

A blast to the past :)

We've been carrying these synthetic benchmarks in our kernel tree since 
2009 because they've been helpful to identify regressions in hot paths, as 
well as quantifying any improvements that have been made for new changes.  
Hopefully they can be useful to others as well.

The synthetic benchmarks are run by loading the module at runtime.  The 
modprobe will fail intentionally so that the module gets insta-unloaded.  
The test results are emitted to the kernel log.

Proposed with permission from Christoph.
