[PATCH v2 0/4] Make input drivers y2038 safe
Reposting the series as I did not hear comments from the maintainers. The series is aimed at making input events y2038 safe. It extends the lifetime of the realtime timestamps in the events to year 2106. The plan is to deprecate realtime timestamps anyway as they are not appropriate for these timestamps as noted in the patch a80b83b7b8 by John Stultz. The series is a result of many discussions with Arnd Bergmann. The design updates the format of the input events read/ written to the device nodes. This structure and the uapi/input.h header file are copied across many userspace libraries. These libraries not only use this struct input_event locally, but also expose interfaces that contain input_event. To maintain backward compatibility with all these interfaces, kernel updates the format of the input events at the dev node to struct raw_input_event. Kernel also maintains the old struct input_event and provides apis to convert between the old and new input event types. The userspace library changes to libevdev, libuinput and mtdev will be posted to the respective mailing groups for review. Once there is a consensus on the design, all the changes dependent on the kernel change will be merged at the same time. Changes from v1: * Updated changes according to review comments. * Posted userspace library changes that go along with the series.
