Crikey - they did what?!

I recall a fascinating article / thread years ago about swappiness=0 not actually meaning what people thought it meant, and explaining why it was (generally) a bad idea. A low number, yes, but not 0.

Doing some research now, and found a blog written by someone bitten by this change back in 2014-04 -- referring to the commit that introduced this in 3.5-rc1. Not clear why the change was made, though, as a) it breaks lots of people's understanding / expectation, and b) if you want to never swap out then just forego the creation of a swap file / partition.
