I am trying to install dm-cache on my CentOS machine. Which dm-cache version should I use. I read on wikipedia as below:
Another dm-cache project with similar goals was announced by Eric Van Hensbergen and Ming Zhao in 2006, as the result of an internship work at IBM.
Later, Joe Thornber, Heinz Mauelshagen and Mike Snitzer provided their own implementation of the concept, which resulted in the inclusion of dm-cache into the Linux kernel. dm-cache was merged into the Linux kernel mainline in kernel version 3.9, which was released on April 28, 2013.
dm-cache is integrated in the mainline of linux kernel. And also dm-cache was written by Joe Thornber, Heinz Mauelshagen and Mike Snitzer and another was written by Eric Van Hensbergen and Ming Zhao, so which one should I use, are both the same, both the version differ in the way it has to be setup. Has any one tried to use both the versions?
