You did not show the "SwapCached:" entry from /proc/meminfo in your output. If that is 0, I could still be correct to expect that "free" shows us the sum of Cached and SwapCached. I don't see what Mike's slab reclaimable would have to do with this, unless some ambitious soul tried to stuff 3 numbers into one and hoped to do us a favor. After all, some look at the 2nd line in "free" for what they could available when it has to be, so by sneaking other numbers into the "cached" value you find that "free" will include that into the "+/-" cache numbers. Wish even more I had the time to investigate. From earlier experiments in http://zvmperf.wordpress.com/2013/01/31/the-nocache-approach/ I still have tools that tell me *which* files are in cache, so we should be able to get the picture right...
