Oftentimes such code commentary mechanically describes list of statements, rather than explaining the idea behind it.
A well-written document should try to describe the idea behind the implementation, rather than the implementation itself. (Yeah, that's challenging)
They don't save much time compared to directly reading the code.
(some random rant of the day)

I see the problem! In Korea, it's considered inappropriate to sign using red ink.
"It is a common Korean superstition that if someone’s name is written in red, then death or bad luck will come to that person very soon."
Should have been blue or black :'(

Linux Kernel Security
linkersec@infosec.exchangeslab: support for compiler-assisted type-based slab cache partitioning
@melver posted a kernel patch that provides an alternative mode to RANDOM_KMALLOC_CACHES called TYPED_KMALLOC_CACHES.
The new mode leverages a Clang 22 feature called "allocation tokens". Unlike RANDOM_KMALLOC_CACHES, this mode deterministically assigns caches to allocations based on their types, and not allocation sites.

https://lore.kernel.org/lkml/CAHk-=wj2WqpPBwpAXo8bj_Hx-NxKMRVTVMUaQis7+Vm6XLRZiw@mail.gmail.com/
For a list of new features, see:
* the LWN brief news entry – https://lwn.net/Articles/1067279/ (Screenshotted below)
* the LWN merge-window summaries – https://lwn.net/Articles/1057769/ and https://lwn.net/Articles/1058664/
* the KernelNewbies 7.0 page – https://kernelnewbies.org/Linux_7.0
And reminder: the jump from 6.19 to 7.0 does not mean anything apart from "Linus ran out of fingers and toes to count on."
