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 series is also a necessary update as glibc is set to provide 64 bit time_t support for 32 bit binaries. glibc plan is detailed at https://sourceware.org/glibc/wiki/Y2038ProofnessDesign .
The series is a result of discussions with Arnd Bergmann and Dmitry Torokhov at last Plumbers.
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 design also updates the format of the input events read/ written to the device nodes. This breaks 32 bit interface to the input events at compile time as preferred by the maintainer.
The userspace library changes to libevdev, libuinput and mtdev will be posted to the respective mailing groups for review.
Changes from v5: * Dropped patch 1, since it has already been applied * Combined patches 2 and 3 * Addressed minor review comments Changes from v4: * Dropped serio hil patch Changes from v3: * Updated uinput to support monotonic time only * Addressed review comments Changes from v2: * Updated the design to break 32 bit interfaces at compile time. Changes from v1: * Updated changes according to review comments. * Posted userspace library changes that go along with the series.
