First of all, sorry for the overly long series that this turned into. I'm currently doing a survey of all code using time_t/timeval/timespec to get an idea of what work needs to be done where, in particular in terms of user interface changes. Lustre is by far the most pervasive user of time types and functions, and I could not even find my way through the code to see what needs to be done other than actually doing that work. On most other subsystems, we try to use montonic times where possible for in-kernel uses. I did not do that here but kept using wall-clock times, in order to leave the debug output and procfs files untouched. A follow-up series could convert a lot of the ktime_get_real_*() to ktime_get_*() to change that if we don't care about the format. There are a couple of things that I left unchanged: - Socket timestamps in drivers/staging/lustre/lnet/lnet/lib-socket.c need to wait for the socket API to be changed first - inode timestamps need to be changed in VFS, which is a larger work - The conrpc selftest has a user interface based on timeval that is hard to change. All patches are based on staging-testing and built-tested on 32-bit arm and x86 as well as 64-bit arm.
