The io_uring subsystem can now store the rings and submission queue in user-space memory.
Ability to mount a file system underneath an existing mount on the same mount point; useful in container scenarios (Merge tag ‘v6.5/vfs.mount’ of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs 5).

I’m about to jump from Ubuntu back to good ol’ Debian. I was planning on testing, but I’ve heard a few times recently that people are running unstable for day-to-day desktop use. Is there any particular reason you went with unstable instead of testing? Any issues so far?
most of the time it works every time. :)
I’m using debian unstable as a desktop OS on all of my 3 regularly used systems: 2 notebooks and 1 desktop. And debian 11 on citrix virtual desktop at work. debian stable on around 200 servers.
I rarely have bigger issues in my day to day usage of unstable which includes surfing, gaming and coding. at the moment my bluetooth headset microphone doesn’t work, which i guess is due to some changes to pipewire but only on my desktop. both my work and private notebook seem to not have issues.
this is one of the worst problems i had in the last 8 years. other then that, if you use apt-listbugs to exclude any updates with serious bugs by pinning them until a bugfree version gets released, you wont have any more issues then you get with arch for example.
