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.
- cgag 10y agoI think for many people without any context that explanation isn't quite enough. jdub's comment explains it quite well though.
- protomyth 10y agoThe 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.
