Article is distressingly lacking on details; following the (correct subset of) links is mandatory.

Interesting optimization. If what they say is true, 30% is a lot, but I wonder how they arrived at those numbers and how well it would scale across various platforms and workloads.

And I count 822 lines changed, not 30.

while not 30, the bulk of the line changes (around 688) are Documentation, Test, and build (like .gitignore update, build script update to include the updated tests, etc)

the kernel changes are around 118, and that includes header file updates.

I like that there are more doc and test updates than code changes.

So how do we enable the feature?
