  I thought it was interesting for: Remove the PG_ZERO flag and remove all page-zeroing optimizations, entirely. Aftering doing a substantial amount of testing, these optimizations, which existed all the way back to CSRG BSD, no longer provide any benefit on a modern system.

    I think for many people without any context that explanation isn't quite enough. jdub's comment explains it quite well though.

      The joys of linking to the original source. Slashdot does have one interesting advantage over HN in that putting a large explanation, often with multiple links, is expected when submitting something. I probably could have found a blog or article with a fuller explanation, but then you get into accusations of submitting "blog spam". I figured this is HN and someone like jdub would come along and write a great explanation if the topic was worth consideration.
