zsmalloc/lzo compressibility vs entropy

2013-03-27 Thread Dan Magenheimer
This might be obvious to those of you who are better mathematicians than I, but I ran some experiments to confirm the relationship between entropy and compressibility and thought I should report the results to the list. Using the LZO code in the kernel via zsmalloc and some hacks in zswap, I measu
