From 2de9d505fb0d53676b6d595e8334a9dcdfda8d12 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 29 Aug 2018 17:47:19 +0200 Subject: rds: store socket timestamps as ktime_t rds is the last in-kernel user of the old do_gettimeofday() function. Convert it over to ktime_get_real() to make it work more like the generic socket timestamps, and to let us kill off do_gettimeofday(). A follow-up patch will have to change the user space interface to deal better with 32-bit tasks, which may use an incompatible layout for 'struct timespec'.
