It's a non-Rust related principle in kernel that:

1. No code shall pass without a caller.
2. No code shall be more generic than its callers require it to be (because we don't hold API/ABI compatibility per version for in-kernel API's).

A non-rustianated opinion about DMA patches: it should be part of patch set that requires DMA.

I.e. I was eager to try it out but there is no payload to test. I did add lei filter to get everything from rust-for-linux matching DMA so looking forward to do this in future :-)

@pinkforest I personally buy my music from Bandcamp rather than stream it from Spotify so doing at least in that sense my part :-) And still buy printed books etc.

@josh yeah, it is super convenient

@vitaut good. competition rules. not having death wishes for C++.

I've been for a while planning for a while to add anonymous inodes but every time I start doing that I noticed similar step as the commits below the top-most are. It's better to work like this up until pieces go to right by themselves.

There's also still too much mess to take any bold actions on the use of locks. It also would need much cleaner starting point :-) This is time-consuming, unproductive but also fun...

We meet again after three week break:

https://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git/log/?h=v4l2-loopback

I collect below the top-most commits that are locked in as pretty much dead obvious changes and the top-most commit (whatever its name happens to be) is the dumpster.

I started this by unpurging the top-most just to recall where I was at. Commit ID's live as I might add a new commit in any position (as deep down in history as possible as it makes sense).

so i heard you wanted a filesystem that is copy on write, in-tree (so not zfs), does not eat your data (so not btrfs) and is not maintained by a certain person (so not bcachefs)?

i present you, ocfs2, or oracle's cluster file system version 2

you say that it's for shared network disks in clusters? here i put it as a root filesystem, on a core 2 duo thinkpad, running off a single usb stick on usb 2.0

If I want to test Ubuntu kernel in a VM what do I need to change in this old snippet of mine:

git fetch --no-tags git://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack refs/tags/cod/mainline/v6.3-rc7:refs/tags/cod/mainline/v6.3-rc7
git checkout next
git checkout -b next-test
git merge cod/mainline/v6.3-rc7
LANG=C fakeroot debian/rules clean
LANG=C fakeroot debian/rules binary-headers binary-generic

The problem: that URL no longer responds.

Venäjän sensuuriviraston johtaja on tyytyväinen siitä, miten Twitter / X on viime aikoina muuttunut

Viraston johtajan mukaan Venäjä saattaa pian taas sallia Twitterin käytön - palvelu on ollut estettynä maassa jo useamman vuoden ajan.

GNU Gold Linker Is Deprecated & Will Be Gone For Good Without New Developers

With the recent GNU Binutils 2.44 release, one of the changes is worth calling out in its own article: the GNU Gold linker is now officially deprecated and is now being segregated to its own extra Binutils package but risks being removed all together without new developer volunteers stepping up to maintain this linker...

@oleksandr right i don't have any work for the rest of the month because right now i pay my own salary :-) i was a contractor. for the next job i'm happy to be an employee again... thus i can play xcom for living... (up until end of this month)

A - DNS record
AA - battery
AAA - battery
AAAA - DNS record

#DNS #Battery #Confusion

@oleksandr hmm... and also played "xcom: enemy within" because still no news on xcom 3...

@oleksandr also rest of the month I look solely Linux as I have no other job up until March (including v4l2 loopback).

@oleksandr yeah, right, well i guess i'm not that effective :-) i looked actually LKML on Wednesday because I have some gap... so I did voluntary work then.

I've said this before but if you need to test something with graphics but don't want to use GPU, try either:

1. https://github.com/emoon/rust_minifb
2. https://github.com/emoon/minifb

They give you display and 32-bit framebuffer. No bullshit. Neither is dependent on the other. They just implement same things.

Even Web is supported (in both) when compiled to wasm (I'd guess).

Sometimes using GPU can really get in the way of testing so good keep in mind :-)
