Hi Andrew,
Good point. 'struct timespec' is not considered year 2038 safe and
unfortunately I recently made the mistake of using it to communicate
timestamps to user space over netlink. :/ The code is still in net-next,
so I will fix it while I can.
Arnd, would it be acceptable to use 'struct __kernel_timespec' instead?
Thanks
