Linux 2.6.22 Kernel Released

An anonymous reader writes "Linux creator Linus Torvalds announced the official release of the 2.6.22 kernel: 'It's out there now (or at least in the process of mirroring out — if you don't see everything, give it a bit of time).' The previous stable kernel, 2.6.21, was released a little over two months ago. New features in the 2.6.22 kernel include a SLUB allocator which replaces the slab allocator, a new wireless stack, a new Firewire stack, and support for the Blackfin architecture. Source-level changes can be tracked via the gitweb interface to Linus' kernel tree."

What is this?

[Whiney Mac Fanboy]

Seriously, what the fuck is going on with slashdot?

I've read & reread the linked articles, and not a single mention of the iPhone - and it's been over 48 hours since an iPhone story. Seriously - it's like slashdot's turned into a linux site, instead of an iPhone site.

Let's not forget our roots folks - just because linux is the big hype story today.

You do justice to your nickname.

You do justice to your nickname.

Thank you, but I do feel that there's a little too much redundancy in my nick. I mean, if I was called "mac fanboy", you'd assume whiney.

For that matter, if I was just called 'mac', everyone would read the implied 'whiney fanboy'

There for you, help yourself.

BTW in short plain english, it adds some voodoo stuff to struct page, removes a lot of metadata cruft from the slab allocator, adds lesser and simple locking after removing most of locks which are not required because of the changes in the cache layer.

So if you are running your kernel on a huge farm of processors of the order of thousand(s), you ll find a remarkable memory saving, which is a big overhead in slab allocation.

HTH

SLUB much better than slab

[Anonymous Coward]

Great improvement! SLUB is obviously better than slab, since it's all uppercase. I get a lot of emails these days using uppercase to distinguish their importance. I think it's a good thing the linux community is catching on to this IT trend.

Re:GPL v3

[Anonymous Coward]

Some other possibly unnoticed effects of the GPLv3 include:
- You can't use a CPU of the same manufacturer that has previously executed GPLv3 code in the same room as a computer running a Microsoft operating system. If you have exhausted all the alternatives and you still need to run your GPLv3-infected hardware in the same room, you can negate this by drawing a chalk circle around the machines running the MS software and sprinkling a ground-up printed copy of the GPLv3 over and around them. This is all standard as per Section 5.
- In the case the Richard Stallman's or any of his buddies' computer blows up (for any reason - read the license for full details), he's allowed to walk into your house and take your computer right off your desk and keep it, even if it has never run GPLv3 code!
- If left unattended, disks containing copies of the GPLv3 can become corrupted and mutate into GPVv3 (General Public Virus version 3), which will assimilate all carbon and silicon-based matter with in a 3 mile radius into a demonic, electronic, GPLv3 spreading zombie ox (or it might be a buffalo - that part is unclear).

This is why we should all boycott GPLv3. It is just too evil and virusy.

it adds some voodoo stuff to struct page
I believe that brings the amount of the Linux kernel containing Voodoo to 13%.

iPhone support?

Crashing soon a kernel near you...

[backwardMechanic]

To quote from the bottom of the page: [The mm-tree] can crash your machine, eat your data (unlikely but not impossible) or kidnap your family (just because it has never happened it doesn't mean you're safe)

I notice the patches being tested include Reiser 4...suddenly the above warning appears a bit more sinister.

Re:New wireless stack? Firewire stack? WTF?

[cerberusss]

I've seen some insightful posts from you so I'm not assuming you're trolling. But this has been discussed to death. There are perfect kernels in the 2.6 series and they're created by your vendor. That's what Linus wants and that's how it goes.
