I made a script that runs 'time ./mmap-perf' 100 times and outputs the
average.  The output on the standard kernel was:
real: 1.022600
user: 0.135900
system: 0.852600
The output after the patch was:
real: 0.815400
user: 0.113200
system: 0.622200
These results were consistent which isn't surprising considering the
fact that they themselves are averages.
What do you think?
