I reduce maintainer burnout by deleting as much of the subsystem as possible.

I found yet another insightful arXiv paper exploring DAMON and finding grateful area to improve. My holiday would never be boring :)

Oh, I shouldn't tag regzbot when a commit hasn't landed in the mainline yet :)
It isn't really a "regression" yet

When patchwork integration is configured, b4 will now retrieve the CI status of each patch as well.

OK, enough joking, time to get serious now https://lore.kernel.org/all/20231113191340.17482-22-vbabka@suse.cz/T/

there are so many batteries I should charge everyday... laptop, smartphone, smart watch and bluetooth earphones.
start to feel nervous when one of them is gone.

So, you want to read LKML with Gmail (experimental, testers needed)

what, there's a script to import linux kernel headers to QEMU.
From commit 412a8245 ("pci_regs.h: import from linux"):
```
It seems to make sense to import pci_regs.h from linux: why maintain our own?
As a first step, move the header to standard-headers, and add it to the update script.

securepaul@fosstodon.orgI'm a little surprised and disappointed that the 2023 Linux Foundation TAB election only has five candidates running for the five open seats. All five of the candidates are existing TAB members.
It would seem like one of the issues the TAB should focus on this year is getting more people interested in TAB participation.

A big barrier to reading and analyzing code is a psychological resistance to reading unfamiliar text

TIL:
DMA in PCI(e) means a device initiates memory read/write transactions.
But how to make a device initiate such a transaction is device-specific (i.e. a device implements a DMA command via its registers)
Wondering if a DMA interface can be added to CXL.io protocol so that page migrations can be done in a peer-to-peer manner without host interference. (in systems with multiple memory tiers)
