Quotes of the week
Being a Linux kernel maintainer has been my proudest professional
accomplishment, spanning the last 19 years. But now we have a
surfeit of excellent hackers, and I can hand this over without
regret.
— Rusty Russell moves on
We're rapidly moving away from the world where a page cache is
needed to give applications decent performance. DAX doesn't have a
page cache, applications wanting to use high IOPS (hundreds of
thousands to millions) storage are using direct IO, because the
page cache just introduces latency, memory usage issues and
non-deterministic IO behaviour.
— Dave Chinner
If we try to make the page cache the "one true IO optimisation source" then we're screwing ourselves because the incoming IO technologies simply don't require it anymore.
Oh, and the patch is obviously entirely untested. I wouldn't want
to ruin my reputation by *testing* the patches I send out. What
would be the fun in that?
— Linus Torvalds, who subsequently tested the patch anyway (thanks to Borislav
Petkov)
