@ljs lol I recall reading it in "Linux Kernel in a Nutshell" book and I was shocked in the same way

@lkundrak Aha, just PLA.

I wanted to create something like this when I was a child, but I had no 3D printers ;)

@vbabka thanks :) but at the same time, on bright side, I have free time that allows me to learn how QEMU/PCI/CXL works without much work pressure.

@vbabka It's not declared thrown away - but no one in the company needs my work, and there is no specific task nor requirement. And I can decide what to do.

So I asked if I'm allowed to contribute my work to upstream community and I was told "No, it's our company's property"

I'm not sure why they even hired (even if it's intern) me.

CONFIG_RANDOM_KMALLOC_CACHES has landed:

CONFIG_SLAB_VIRTUAL is coming:

Sorry for what you had to go through.

Reminds me of my parents' lives. It hasn't been long since the quality of life in South Korea greatly improved.

My father and mother couldn't even finish high school because they had to work to support their family.

They tried their best not to make me (and my sisters) experience the same thing. I am always thankful to them.

These days the situation is much better. Many people are not forced to work and give up studying. And on the internet you can find most things you need for studying something.

writing code that will not be used at all is utterly frustrating and akin to creating garbage.

It has happened at last: after many iterations, that x86 shadow-stack patch series has been accepted into the mainline for 6.6:
