Linux: 2.6.22-rc1, "You Name It, It's There"
Sunday, May 13, 2007
The latest Linux kernel release is upon us: 2.6.22-rc1. This new release sports a plethora of features, and as Linus puts it, "architecture updates, drivers, filesystems, networking, security, build scripts, reorganizations, cleanups.. You name it, it's there." From the Linux kernel mailing list (full announcement):
Ok, the merge window has closed, and 2.6.22-rc1 is out there.Overall, an impressive release. Read more @ kerneltrap.org.
The diffstat and shortlogs are way too big to fit under the kernel mailing list limits, and the changes are all over the place. Almost seven thousand files changed, and that's not double-counting the files that got moved around.
Architecture updates, drivers, filesystems, networking, security, build scripts, reorganizations, cleanups.. You name it, it's there.
You want a new firewire stack? We've got it. New wireless networking infrastructure? Check. New infiniband drivers? Digital video drivers? A totally new CPU architecture (blackfin)? Check, check, check.
That said, I think (and certainly hope) that this will not be nearly as painful as the big fundamental timer changes for 2.6.21, and while there are some pretty core changes there (like the new SLUB allocator, which hopefully will end up replacing both SLAB and SLOB), it feels pretty
solid, and not as scary as ripping the carpet from under the timer infrastructure.
So give it a good testing. We'll see how the regression tracking ends up working, but in order to actually track that, we want people actively testing -rc1 and making good reports!
