Following up to feedback on his merge plans [story], Andrew Morton [interview] posted an updated summary of what he is pushing upstream for inclusion in the upcoming 2.6.22 kernel. His list included, "a few serial bits, a few pcmcia bits, one little security patch, the blackfin architecture, small h8300 update, small alpha update, swsusp updates, m68k bits, and lots of UML updates." He also noted that he'll push some of the memory management queue including, "an enhancement to /proc/pid/smaps to permit monitoring of a running program's working set. The SLUB allocator, it's pretty green but I do want to push ahead with this pretty aggressively with a view to replacing slab altogether. Generic pagetable quicklist management. We have x86_64 and ia64 and sparc64 implementations, but I'll only include David's sparc64 implementation here. I'll send the x86_64 and ia64 implementations through maintainers."

Following the release of the 2.6.21 kernel [story] Andrew Morton [interview] posted a list of patches in his -mm kernel, summarizing for each his plans as to whether or not they wil be pushed upstream for inclusion in the upcoming 2.6.22 kernel. He noted, "the overall stability in recent -mm's was not sufficiently high and we ran out of time to find all the bugs. I shouldn't have merged all those patches last week - they contained an exceptional amount of garbage. This all means that more bugs than usual will probably leak into mainline, and we'll have to fix them there." He went on to add, "I've been ducking most non-bugfix patches recently. I have ~200 feature and cleanup patches queued for later consideration, so people who sent those will be hearing from me eventually."

Linux: New Intel PRO/Wireless 3945ABG Driver

James Ketrenos announced a new 80211 based driver for the Intel PRO/Wireless 3945ABG network connection adapter, "this new driver uses the new d80211 subsystem previously only available as part of the wireless-dev tree." An earlier incarnation of the driver code was much criticized for its inclusion of a userland binary-only daemon [story], prompting the OpenBSD project to create their own blob-free driver for the card [story]. "The [new] iwlwifi driver for the 3945 does not require the user space daemon, but does require a new microcode image," James explained, "over the past year we were able to make the necessary changes to the microcode used with the 3945 such that we were able to remove the regulatory daemon."

When the question was asked if the driver was going to be pushed for inclusion into the mainline kernel it was noted, "hmmm...I think we need to spend a cycle or so in -mm. 2.6.22 seems more likely for mainline." Pavel Roskin suggested, "iwlwifi is surprisingly good for a just announced driver. It worked for me from the first attempt, and that's the first d80211 driver to do so. In my opinion, it should go to wireless-dev as soon as possible so it can go to -mm together with other drivers."
