=== Highlights === * Got buy in from Brian & Arve on my alternative monotonic evdev input timestamp patch. Resent to input list and maintainer. Still haven't heard anything back from maintainer about merging it or not. I suspect this will end up having to wait for 3.4
* Worked to get the Android sub-team wiki page started up. https://wiki.linaro.org/WorkingGroups/Kernel/AndroidUpstreaming
* Synced with Rafael about his wakelock/pm_stay_awake migration plan. Likely a good candidate for alarmtimer interface testing.
* Ran the weekly Android sub-team meeting (over email) with Anton.
* Andrew Morton pushed my merge_config.sh script for merging. Unfortunately it was sent to the kbuild maintainer and not to Linus, so its unlikely to make it in for 3.3. The patch still is pending in -mm.
* Synced with Andrey, Nico and Deepak on Linaro kernel transition
* Reposted merge_config.sh script and sent it to Andrey for inclusion into the linaro kernel. Looking to try to handle inconsistent config issue which has been causing trouble recently.
* Tried to push 2 RTC fixes as well as some timekeeping cleanup patches to Thomas for inclusion in 3.3. So far no response, so I've pinged tglx again.
* Looked into lockdep warning I was getting with fadvise volatile implementation. After spending a bit of time, I couldn't sort it out and tried to see how ashmem avoids it. Ends up ashmem trips the same lockdep warning and calling vmtruncate_range from a shrinker is the problem. Not yet sure how to avoid this yet, but decided to table it for now.
* Started work on a range-tree algorithm for better managing the volatile page ranges used with the fadvise volatile mapping alternative to ashmem. Got some reasonable progress on an initial userspace algorithm. I feel like I'm back in college (zig-zig/zig-zag/what?).
=== Plans === * Continue working on range-tree algorithm, trying to add self-balancing to the tree. If that gets finished, try to integrate it into the kernel & my fadvise code.
* Ping kbuild maintainer about merge_config.sh patch status
* Send out alarmtimer rework to greg & android devs for review
=== Issues ==== * Tried to provide some workarounds for sched_clock issues that are cropping up on arm. Likely we need to add a middle-to-largeish work-item for someone in Linaro to fix the generic sched_clock implementation, as I suspect it isn't going to just go away. Unfortunately I don't have enough time to dig in on it right now.
