From 071eee45b1650d53d21c636d344bdcebd4577ed2 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 28 Sep 2015 22:21:29 +0200 Subject: ntp/pps: replace getnstime_raw_and_real with 64-bit version There is exactly one caller of getnstime_raw_and_real in the kernel, which is the pps_get_ts function. This changes the caller and the implementation to work on timespec64 types rather than timespec, to avoid the time_t overflow on 32-bit architectures. For consistency with the other new functions (ktime_get_seconds, ktime_get_real_*, ...), I'm renaming the function to ktime_get_raw_and_real_ts64. We still need to convert from the internal 64-bit type to 32 bit types in the caller, but this conversion is now pushed out from getnstime_raw_and_real to pps_get_ts. A follow-up patch changes the remaining pps code to completely avoid the conversion. Acked-by: Richard Cochran Acked-by: David S.
