Ah, even that old. I thought it's just been a couple of years. Interesting that Linus claims the opposite.

(Not that it would have any practical meaning for me. No device except my phone swaps. And that uses zram.)

Yup. There was a massive rewrite of the swap setup in the 2.4/2.6 era. I always thought it was 2.4.10-ish, maybe that's why I could never find anything to back me up, maybe it was 2.6.10.

Anyways, Linus took a look at the spaghetti that was the original swap code that had been there since forever, threw his toys out the pram, threw the code out of Linux, and waited for the dust to settle :-)

So we got a nice, clean, well-written and well-thought-out memory/swap system roundabout that point in time. It wasn't pretty while it was happening, though ...

Cheers,
