Hopefully bcachefs will be merged with 6.6.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For those who may not know, bcachefs (bcachefs.org) was written by the same developer as bcache (wikipedia.org) - TIL! I was always confused when reading headlines about bcachefs but never looked into why someone might give their filesystem such a conflicting name. Now it makes sense. I've used bcache briefly and it worked really well for my use case. Anyone using bcachefs that can speak to their own experience? How does it compare to btrfs?
I love it. I have a pool of 9x10tb spinning rust as bulk storage (background target in bcachefs terms) and 6x3.84tb SSD as cache and metadata (foreground, promote, metadata targets). It's proven to be incredibly solid, I've written tons (on the order of 50+tb) to the FS and actually hit a few edge cases during my early testing in terms of scaling limits and the like.
This ~100Tb array replaced a Synology-flavoured btrfs 30Tb which had been running up against capacity limits for a while. I looked into alternative FSes: btrfs RAID wasn't quite there for me, and zfs won't be mainlined.
The only 'not 100% stable' feature is Erasure Coding, which I look forward to enabling at some point in the future.
wow! happy to hear that. May have to play around with it before I fully commit.
The new EEVDF scheduler would also be nice.
This is the best summary I could come up with:
Linux 6.5 was just published rather than going into overtime without any extra release candidate.
Linux 6.5 has many great features from the AMD P-State EPP driver default rather than ACPI CPUFreq for Zen 2 and newer supported AMD Ryzen systems, initial USB4 v2 enablement, initial MIDI 2.0 kernel driver work, more Intel hybrid CPU tuning, and a whole lot more.
See the Linux 6.5 feature list to learn more about all of the great changes in this end of summer 2023 kernel debut.
With nothing overly scaring coming up, Linus decided to go ahead and release Linux 6.5 stable.
Now it's onward to the Linux 6.6 cycle with many features to look out for with what will be an autumn 2023 kernel release.
The timing now of the Linux 6.6 merge window for the next two weeks will mean that it runs through the US Labor Day holiday when a number of the kernel developers may be taking time off for holiday.
The original article contains 222 words, the summary contains 163 words. Saved 27%. I'm a bot and I'm open source!
Does anyone have a quick ELI5 for the AMD P-state or a link to some good info around it? Seems people are excited about and I've been out of the news cycle loop lately.
