"Ok, the merge window has closed, and 2.6.22-rc1 is out there," Linus Torvalds announced on the Linux Kernel Mailing List. He noted that there were a large number of changes, "almost seven thousand files changed, and that's not double-counting the files that got moved around." As to what was changed, Linus summarized, "architecture updates, drivers, filesystems, networking, security, build scripts, reorganizations, cleanups.. You name it, it's there." He went on to add:
"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."
