Hi,
I've created a new mailing list on the Linaro mailing list server for discussing the kernel patches for y2038:
https://lists.linaro.org/mailman/listinfo/y2038
Please join if you are interested in discussing these or want to send patches. The intention at the moment much to keep this list explicitly open to newbies, so we will get a lot of incorrect patches there along with other patches. Patches can get sent here for an initial review before they get sent to the real maintainers, or you can put the list on Cc when sending a patch that should be applied and you already know what you are doing.
We already got a lot of patches last year through the Outreachy (then known as OPW) application process, and John and I also use this work as part of our Linaro job to train new kernel developers.
There also a wiki page at http://kernelnewbies.org/y2038 to describe what we are doing, and anybody who wants to help out here is welcome to contribute patches on this list.
Arnd
